Hi everyone, Dong Ngo’s here! (Weird last name? Dong “Know” will do.)
The original spelling of my name is Đông Ngô, and its correct pronunciation, which is impossible to many, is not even close to sharing the sound or the meaning of what you might be thinking of right now. Thank you, English!
Who is Dong Ngo?
Some of you probably remember me as CNET‘s “router guy” during its heyday. Fair enough! From late 1999 to mid-2017, I managed product testing at CNET San Francisco HQ, where I also reviewed networking devices, among other responsibilities.
I published my last piece of content for the tech site on June 10, 2017. CNET might have unilaterally changed or updated articles under my name since.
What you sure don’t know is how my obsession with technology started.
As a teenager, I ran into a repurposed cardboard piece with a life-size QWERTY keyboard drawing on it. Upon finding out what the picture was supposed to be, I used it to practice typing with all ten fingers, just for fun… Years later, I got my hands on a real keyboard with a computer attached, and my life changed forever.
In a way, that piece of cardboard was my first touchscreen. Now, like many of you, cutting down on screen hours is my daily struggle.
Your visit to Dong Knows Tech will be worth the effort. I’m not going to waste your time!

A bit of personal stuff
I was born and raised in a tiny village in North Vietnam, surrounded by paddy fields. The part just before I arrived had been ravaged by American air supremacy during the American war.
For years, we had nothing, tech-wise and non-tech-wise.
I spent most of my childhood as a farmer, without electricity or running water. I remember being ready to eat a bit more at any given time as a kid—I was just always hungry—and having no experience with shoes until I was 17.
Now, I live with my little family—a wonderful lady and three children—in the San Francisco Bay Area. It has been a long and memorable journey to that “American dream.”
As a teenager, inspired by American music—specifically, Michael Jackson’s “Black or White” and the Eagles’ “Hotel California”—I learned English. It’s not my first language. (Not even my second or third, so to speak.) That said, once in a while, please excuse my French! 🙂

What you can expect from Dong Knows Tech
“This Dong guy knows tech!” is something you might tell yourself after reading my posts. And hey, I do tech for a living, mind you! But that’s not the point of this website.
The origin of “Dong Knows Tech”
My last name is often mispronounced as “No,” which sounds similar to “Know,” so a good friend suggested “Dong Knows Tech,” and I found it a clever pun—at least it’s easy to say and remember.
Contrary to the name, I have no desire to say or prove that I know better than anyone. Everyone should and can figure things out on their own if they want to.
“Dong Knows Tech” is an alternate spelling of “Dong Ngo’s Tech.” By the way, if you visit dongngostech.com, the original domain name for the site, you’ll also end up here.
What you should pay attention to is that I do my research and review products independently.
Dong’s promise
I remember every promise I’ve made—I don’t make one easily. Here is one:
Reviews and how-to posts on this website are based on thorough, firsthand testing or real-world experience. You’ll find no bullshit, no clickbait, no patchwriting, no pointless listicles, and no product pushing/placement here.
Specifically:
- I don’t intentionally mislead you for personal gain through views and clicks, or any other means. I don’t do clickbait.
- I don’t accept money to say good (or bad) things, nor do I say good things just to sell something. (I get many offers, which is why my contact page seems unfriendly.) In other words, I’m not one of those “influencers.”
- I don’t publish just marketing materials, specs, or commentaries and call it a review.
- I don’t steal content from other websites in any form whatsoever.
- This website does not use AI or bots to write articles or regularly change the introductions or dates of stories to make them “SEO friendly”. It also strictly does not publish content with ulterior motives. Specifically, it:
- does not accept guest posts with backlinks.
- does not accept sponsored posts with third-party content.
- does not buy links or accept link exchange.
After almost two decades in the mainstream tech news and reviews, I understand their not-so-savory secrets and the endless online shenanigans. You will not have to deal with that on this website.
Technology is my passion
I write about tech because I love it, not because I have to or need to. Although I have nothing against hard-earned wealth, I didn’t start this website with the intention of becoming rich. I only hope it makes enough money to justify my time.
Every piece of hardware or software I mention on this website is there because I love it or the idea of it. It’s a type of personal attention you won’t find anywhere else.
In short, “Dong Knows Tech—And THAT is Good for YOU!” is real. I mean it.
That is, of course, if you spend time and read what I have to write. Otherwise, it is only good for somebody else! The “no-nonsense” notion of the site applies to both sides. Keep that in mind!

Disclaimers
The tech world is fluid—things can change quite dramatically over time. You’ll notice that I frequently update many posts with new, up-to-date information, but nobody can keep track of everything or test every scenario.
The reviews and how-to posts on this website are accurate to the best of my knowledge, applicable to the time of publication, and done with the best intentions. However, they are not necessarily error-free or mistake-free.
The point is that I can make mistakes, although I’m always working hard to avoid them.
So, use the content at your own risk. I assume no responsibility for any consequences arising from your voluntary consumption of the information posted here. Consider yourself warned.
I can tell you from experience that it’s OK to make mistakes as long as you learn from them. In that case, a mistake is better than nothing at all.

Disclosure
Dong Knows Tech’s website contains affiliate links from Amazon and Walmart, as well as online ads managed by Mediavine.
The affiliate links may earn the site small—tiny—commissions at no additional cost to readers when they click through and make a purchase. All links to Amazon and Walmart on this website are affiliate links—that’s automatically the case. When possible, that’s made extra clear via a shopping icon (🛍️) prefix.
Occasionally, the site may also accept paid static ad banners—for a fee—that are not part of the programmatic ad services mentioned above.
Dong’s sincere note on ads and affiliate links
I don’t want you to buy something from an online store solely to support me, nor do I ever coerce or trick you into spending money on anything.
But, if you find a good product you’d like to buy anyway, it helps my work if you find it via an Amazon or Walmart link and make a permanent purchase within 24 hours. You can probably even bookmark a link for later.
As for the ads, I don’t directly manage them. The ad network does that. A few things to note:
- Ads on this website, managed by Mediavine, are all safe and non-intrusive. View them for yourself! You can report an inappropriate ad by clicking the icon in the lower right corner of each ad.
- The number of ads displayed is based on specific settings, and I’ve already selected the option that provides the best user experience.
- Online ads are a numbers game. The site needs to reach a certain number of ad impressions—in the millions over a period—to start generating revenue. And then, after over 60 days, I only get to keep a portion of it.
- The higher the impression levels, the higher the percentage I’m allowed to keep. However, the amount needs to reach a certain threshold for me to sustain the site.
Compared to mainstream tech sites, Dong Knows Tech has modest viewership and revenue, which vary monthly. It has many fixed expenses, including almost twenty annual and monthly paid services—hosting, security, backups, anti-spam, image compression, caching, etc.
If you appreciate the site’s honest content, please consider supporting it by displaying ads. Thoughts, prayers, and compliments are appreciated, but they alone are not enough to absorb the operating costs.
Ads, ad-blockers, and my ad-blocker detector
Since late March 2022, an ad-blocker detector has been added to the website—only in certain parts or on certain days—asking you to allow ads. I thought long and hard before making that decision. I knew some readers would find it annoying.
In addition to stealing financial resources from this website, many ad-blockers also block non-ad elements, which, among other things, causes the site’s analytics to be incorrect, further adversely affecting its value.
It’s complicated, but if, for some reason, you believe ad-blockers keep you “safe,” which is debatable, also keep the following in mind:
For ad-blocking to work, the software needs you to agree to give it access to your online activities and browsing records—there’s no way out of that. As a result, the software owner knows what you do with the browser.
While good online ads can still be distracting, a (bad) ad-blocker can silently track your browsing activities and personal information. The blocking software needs to generate benefits for its creator, just like the content you’re viewing.
The point is that you’ll end up having to “pay” for the information, one way or another. Why not support the upfront, transparent, and likely less costly party? Mind you, that party also creates content that benefits you.
The ad-blocker detector serves as a reminder, not a challenge. If you definitely don’t want to see it, please consider subscribing.

“How do you get products to review?”
I often get this question and want to be completely transparent on this front.
I buy many, if not most, of the products I review with my own money. However, over the years, vendors have increasingly offered to ship the hardware to me, and I sometimes send them requests.
In this case, while I appreciate the timeliness—I tend to get the product before the public—I make it clear that I’ll test them thoroughly and evaluate them impartially.
In fact, I often send them to this page—we’re literally all on the same page.
“What do you do with the device post-review?”
That depends.
I treat those I buy the way anyone does theirs—it’s nobody’s business. But for the sake of transparency:
Sometimes, I return them if I finish the reviews quickly enough, there’s no need for additional testing or personal use, and the logistics, including return policies, work out.
And that’s a big if since, among other things, I take my time in testing, and I often buy multiple units to avoid hardware defects and test different scenarios. The point is that I’ve usually had to account for them as operating costs.
Once in a while, a friend or a local reader offers to buy one from me to support my work. However, it’s generally a long game of numbers.
Within a few months, the revenue from ads and Amazon affiliate links from individual reviews has never been enough to cover the cost of the hardware. But over a year, the combined revenue of all reviews might get (significantly) more than the total hardware cost.
I’d hope so, anyway. It’s not a guarantee.
Those vendors send me, I generally prepare to ship them back, though that might not always be the case due to various reasons. (Some vendors don’t want their stuff back.)
In all honesty, repacking and shipping can be a hassle. I’d rather not have to do that for the sake of efficiency. That’s not to mention that I have three little children who need a lot of attention.
If a return is unnecessary and the device is not broken after testing, I may continue to use it for myself, friends, and family for further long-term evaluations. That is how I’ve been able to publish posts with extended or extensive hands-on experience or comparison posts on products released months or even years apart, as you will note.
Still, inevitably, I’ve ended up with a sizable collection of reviewed products in my garage—one can use only so many Wi-Fi routers. Occasionally, having them readily available can become quite handy for a spontaneous project. I generally try to have creative and efficient ways to deal with these hardware “surpluses.” Eventually, I recycle them as e-waste.
The point is this: As a principle, I don’t sell review hardware samples for cash. The only benefit I gain from these “free” products is the related experience and real-world knowledge I share on this website, and whatever benefits that sharing brings. The ball is in your court.

How you can support Dong Knows Tech
Thank you for considering a donation to support this website. Financially, you can donate here.
The devil is in the details. Running a tech site, especially one free of nonsense, involves many things and substantial financial costs. It’s also time-consuming.
I am involved in all aspects of Dong Knows Tech, including the site’s design, functions, and maintenance. It’s a hobby, a passion for tech—you’ll note the extreme level of attention to detail if you pay attention.
Sure, you can call it a labor of love, and it’s absolutely true. But, frankly, even love, no, especially love, can’t survive just by itself—it takes a village.
That said, to support my work, please:
- Take your time to read my articles. If you skim over them, you’ll miss a lot. You’ll notice that I put a lot of effort into my writing. It’s only fair that you do your part in the reading.
- Report typos when you run into one by selecting (highlighting) the text in question and hitting the red button to the right of the screen. I proofread myself, which is always challenging. Again, English is not my native language, and I’m still struggling with it.
- Turn off your adblocker—ads help me make money.
Also, please let me know when you encounter websites that use this website’s materials without properly citing the source.
Finally, I welcome suggestions and appreciate constructive criticism. Please keep them coming!
