He scratches phones with a razor blade, burns them with a lighter, and bends them with his bare hands. Two-point-nine billion people have watched. The question was never "will this break?" It was "why does this matter?" - and Zack Nelson has been answering that quietly, methodically, one teardown at a time.
In 2012, Zack Nelson's Jeep broke down. A mechanic quoted him $1,000 to fix it. He fixed it himself for $80 - and filmed the whole thing. He posted the video to a YouTube channel he'd just created, named it JerryRigEverything after his grandfather Jerry, who was famous in the family for improvising fixes with whatever was at hand, and earned approximately five cents that day.
He kept filming. Cars. Motorcycles. Computers. By the time he was deep into his junior year at Utah State University - where he was studying Business Administration while working full-time at a cell phone store - he'd posted 100 videos and had 2,000 subscribers. The math was not inspiring.
Then he noticed something: everybody has a phone. Not everyone fixes Jeeps. The pivot to smartphones wasn't strategy - it was observation. He started scratching, burning, and bending phones on camera. Methodically. With a Mohs hardness pick set, a lighter, and his hands. His iPhone 7 scratch test went to 16 million views. The channel went to 4 million subscribers. Then 6 million. Then, after his employer closed and gave him four months of severance, he made the call: full-time creator. No backup plan.
When JerryRigEverything crossed 30,000 subscribers, he quit his day job. By any rational measure, that was early. By his measure, it was right on time.
You run your own business; you can choose your own hours - as long as it's all of them.
- Zack NelsonThe channel's signature format - Level 1 scratches, Level 2 scratches, deeper grooves at Level 3 - became a kind of liturgy for tech reviewers and curious consumers alike. It answered a question nobody was asking out loud but everyone wanted to know: what happens when real life meets this device? Nelson made that test visible, repeatable, and oddly satisfying to watch.
His team today is three people: Zack, one editor, one social media manager. A typical phone video takes 10-12 hours. Major build projects exceed 100 hours. The channel posts consistently, which is the only advice Nelson gives to aspiring creators: "Consistency." He doesn't dress it up.
Nelson's testing framework is consistent across every device, every brand, every price point. No favoritism. No sponsorship influence on results. The same Mohs pick set. The same lighter. The same hands.

Cambry Kaylor was 18 when a vaulting accident left her paralyzed. She and Zack married in 2019. Within months, he'd built her a custom off-road electric wheelchair from scratch - a fully electric, super-quiet accessible bike that could go 12 mph with a 10-20 mile range. The video went to 12 million views on Facebook and 5 million on YouTube.
Most people would have stopped there. Nelson incorporated. He founded Not-a-Wheelchair in 2020 to mass-produce The Rig - and then just kept building.
By April 2026, he'd launched the Paradox wheelchair line: ultra-custom, lightweight manual wheelchairs starting at $999, built in the USA in as little as 3 days. The comparison to traditional custom wheelchair pricing - which typically runs $3,000-$7,000 and takes months - is stark. Nelson estimates the project has already saved the wheelchair community over $2 million.
The real-time 3D configurator on the Not-a-Wheelchair website lets users build their exact chair and see a rendered model before ordering. "Nobody else in the galaxy has a real-life, real-time wheelchair configurator like we do," Nelson said at launch. "How you see your rendered chair in 3D is exactly how we will ship it."

In 2022, Nelson announced he'd saved $75,000 from his YouTube earnings and was using it to build a community library in Budalangi, Busia County, Kenya. The project started with his "uncle" Philip, a Kenyan who had moved to the US to study and wanted to give back to the community where he grew up.
The library - full-size, four rooms - completed construction in early 2023. It serves ten elementary schools, six high schools, three colleges, and the surrounding community. It is the only library within a 100-mile radius of Budalangi.
Nelson solicited book donations from his audience - fiction, non-fiction, dictionaries, encyclopedias, textbooks - and documented the entire build on his channel. A library built by a man who gets paid to break phones, funded by 2.9 billion people watching him do it.
$75,000 from YouTube. One library. The only one within 100 miles. Not bad for a channel that started at 5 cents a day.
