I bought the THINNEST Tech in the world.

Feels surreal and responds shockingly well for e-ink, but he was unsure how to rate it and the pen and cover push the price up.

Astonishingly thin and light, but the dim screen and weak speakers make it feel like a dummy unit.

A custom PC built into a motorised desk with electrochromic glass and top-end parts, though not the thinnest thing in the video.

A pocket printer that is fast and prints edge to edge, which impressed him.

Wallet-sized earphones that are impressively slim, though he wondered about battery life.

A strange flattened camera that feels solid and takes quirky, old-school style photos.

A record-thin speaker, 1.1cm, with surprisingly full sound and an eight hour battery.

Turns any object into a speaker using vibration and delivers surprising bass.

Extremely thin folding sunglasses, 0.9cm folded, so thin he felt they could slice fruit.

Sci-fi looking 0.8cm glass keyboard with no key travel, so not the best to use.

A very thin 1080p portable display that feels premium, with an aluminium and glass shell.

Very thin sleep earbuds that fade music out and track sleep, and he was a big fan on first impression despite average sound.

A 0.5cm mouse that is an incredible novelty, but he struggled to see who would buy it.

Credit-card sized 3,000mAh power bank with built-in USB-C cable, not as useless as it sounds.

A 0.15cm wallet that is very cool but borders on being a 3D printed clip.

The coolest piece of tech he has ever held: a fully working, flexible Android device barely thicker than paper.

A mouse mat so thin it feels like gripping air, and he found it ridiculous.
