For a specific part you’re about to buy, Gamers Nexus tests harder than anyone. Every subscriber figure below was checked on July 28, 2026, and every channel here had been posted within the previous month.
Most lists of the best youtube channels stack up ten near-identical gadget reviewers. They quote subscriber counts with no date attached, and they never mention who paid for the review unit. This one splits the picks by job, says what each channel is bad at, and shows you how to read a disclosure. There is more on this in Best Apps for Self-Improvement.
Quick answer: the pick for each job
| What you want | Channel | Why it wins |
| Gadget reviews | Marques Brownlee (MKBHD) | Clearest verdicts on phones, laptops and wearables |
| Component buying advice | Gamers Nexus | Repeatable bench data and a published ads policy |
| Household product testing | Project Farm | Declines all sponsorships and free samples |
| Repair and DIY | iFixit | Step-by-step teardowns tied to real parts |
| Security and privacy | Network Chuck | Hands-on labs you can rebuild at home |
| Programming | Fireship | Fast, current, no filler |
| Science and curiosity | Veritasium | Deep research, genuinely well shot |
TL; DR
- Twelve channels, six jobs, all confirmed active on July 28, 2026.
- Subscriber counts are dated. Treat any undated figure you see elsewhere as stale.
- Independence beats production value. Check disclosure, review-unit policy, and affiliate links.
- One pick for most people: MKBHD. One pick before you spend money: Gamers Nexus.
How we picked these channels?
Three filters. Each channel had to be published this year, cover a job a reader actually has, and hold up to a look at how it makes money. That last filter cut several popular names whose rankings track affiliate commissions more closely than test results do.
We also spread the list across repair, security, programming, buying advice and science instead of six versions of the same phone review. If you prefer reading to watching, our roundup of trusted tech review sites covers the written side of the same question.
Gadget reviews: MKBHD and Dave2D
Marques Brownlee (MKBHD) sits at 21.1 million subscribers across 1,830 videos, with 40 million views over the past 30 days. His flagship phone and laptop reviews are the clearest short verdicts on YouTube, and he separates “I like this” from “you should buy this” better than almost anyone.
What he’s bad at: depth. A 15-minute MKBHD review will not tell you the sustained thermal behavior of a laptop. He also reviews at the premium end, so budget shoppers get thin coverage.
Dave2D (3.69 million subscribers, 839 videos) is the better second subscription. He goes further on thermals, keyboards, screens, and port selection. He also says plainly when a laptop is a bad buy. His weak spot is breadth: he covers laptops well and everything else occasionally.
Buying advice: Gamers Nexus, Hardware Unboxed and Project Farm
These three exist to stop you from wasting money.
Gamers Nexus (2.62 million subscribers, 3,283 videos) publishes repeatable bench data, tears down cooler mounting pressure, and has spent years investigating manufacturers who misbehave. Its advertising policy states plainly that it does not make infomercials.
An ads manager sits between sales and editorial, and direct advertising from AMD; Intel and NVIDIA are blocked outright. Length is the downside. A single GPU review can run for 40 minutes, though that’s cheap insurance against a bad $400 purchase.
Hardware Unboxed (1.17 million subscribers, 2,400 videos) is the faster read on graphics cards and monitors, with large comparison sample sizes. It’s dry, and it rarely covers anything outside PC gaming hardware.
Project Farm (3.89 million subscribers, 523 videos) is the outlier here. Its channel description credits Patreon support with letting the creator “decline all sponsorships and promotional items from manufacturers”. That policy is why its battery and tool tests carry more weight than their production value suggests. Tests are homemade rather than lab-grade, so read them as strong evidence, not proof. Pair its buying advice with a category guide such as our home WiFi router picks if you need a shortlist first.
Repair and DIY: iFixit and Louis Rossmann
iFixit (1.27 million subscribers, 1,080 videos) films teardowns that match written guides and parts kits. That pairing makes it the rare repair channel you can act on the same afternoon. It’s promotional by nature, since iFixit sells tools. Watch it for the procedure and price the parts elsewhere.
Louis Rossmann (2.62 million subscribers, 4,260 videos, 12.9 million views last month) does board-level repair and right-to-repair advocacy. His technical videos are excellent. Commentary videos wander a long way off topic, and you’ll need patience for the tone. For a problem you’re facing tonight, our guide to a PC that won’t turn on is a faster route than an hour of soldering footage.
Security and privacy: NetworkChuck and Techlore
NetworkChuck (5.32 million subscribers, 606 videos) turns networking and security certifications into labs you can rebuild on a spare machine. He’s genuinely good at making a hard subject approachable. He’s also heavily sponsored, and VPN and hosting sponsors appear often enough that you should treat product mentions as advertising until proven otherwise.
Techlore is much smaller at 314,000 subscribers and 673 videos, with 631,000 views in the past 30 days. It covers threat modeling and browser hardening without hype. It also revisits old recommendations when a service changes hands. Pacing is slow, and video quality stays basic.
Both channels tell you what to install. Deciding which suite to trust is a separate question, and our tested antivirus picks answer it for Windows and Mac.
Programming and digital skills: Fireship and freeCodeCamp
Fireship (4.24 million subscribers, 827 videos) compresses a framework into two minutes without dumbing it down. Use it to decide what to learn. Don’t use it to actually learn something, because the pace is far too fast for a beginner.
freeCodeCamp.org (11.8 million subscribers, more than 2,300 videos) is the opposite: full multi-hour university courses, free, including a complete Harvard CS50 run. Quality varies between contributors, and some older courses cover versions that have since moved on. Check the upload date before you commit a weekend.

Science: Veritasium
Veritasium (21 million subscribers, 518 videos, 66 million views last month) is the one entry you watched for pleasure rather than homework. Derek Muller researches hard films well. He also corrects himself in public when he gets something wrong. Two videos a month are a slow schedule, and the physics explainers occasionally simplify past the point some specialists accept.

How to judge a tech channel’s independence?
This matters more than it sounds. According to the Pew Research Center, 35% of U.S. adults said they regularly get news on YouTube in its social media, and a News Fact Sheet published September 25, 2025, from a survey fielded that August. For a third of American adults, the subscription list doubles as a news diet. Four checks, in the order they’re worth doing:
- Find the disclosure before the review starts. The Federal Trade Commission is blunt about the standard in its Disclosures 101 guidance, last updated December 3, 2024: “Financial relationships aren’t limited to money. Disclose the relationship if you have anything of value to mention a product. A free unit counts, and so does a discount or a paid trip.
- Ask what happened to the review unit. Channels that buy their own hardware or return loaned samples usually say so on camera or on a policy page. Silence is not proof of anything, but a stated policy you can read is worth real credit.
- Watch for affiliate-driven rankings. Does the top pick move whenever a commission rate moves? Does every product in a ten-item list carry a store link, with no losers anywhere? Then the ranking is a storefront.
- See whether they publish negatives. A channel that never gives a bad verdict to a brand it works with has told you what it is.
Check the upload date before you subscribe.
Roundups age badly. Tom Scott still turns up on “best of” lists as a weekly watch, but he ended his ten-year weekly run in January 2024 and posts only occasionally now. Rooster Teeth, another regular on older lists, shut down entirely.
Subscriber counts rot the same way. Any figure without a date attached could be two years old, which is why every number in the table above carries the day it was checked.
Our verdict
For most people, MKBHD plus Gamers Nexus is the whole answer: one channel for what’s worth wanting, one for whether the specific part is worth buying. Add iFixit if you own anything you’d rather repair than replace, and Techlore if privacy is on your mind.
Pick two from the table today, watch a full video from each, and check the disclosure in the first 30 seconds. That habit will teach you more about a channel than any list can.

Frequently asked questions (FAQs)
Start with MKBHD for context, Dave2D for buying decisions, and Fireship if code interests you. All three explain things clearly without assuming prior knowledge.
Yes. Each one had uploaded within the 30 days before July 28, 2026, and the growth figures quoted come from channel statistics checked that day.
Yes. The FTC treats anything of value as a material connection that needs disclosing, including free or discounted products, even when the brand never asked for a mention.
NetworkChuck for hands-on security labs, Techlore for personal privacy, freeCodeCamp for structured programming courses, and Fireship for keeping up once you know the basics.
Look for a list where nothing loses, and every entry carries a store link. Then check whether the order shifts between updates with no new testing behind it.
