I bought every gadget I saw on Instagram

The printed results are mind-blowing, but the machine is very expensive and he doesn't know what he'd use it for.

Cleans screens well and sticks to the back of a phone, though they pick up grime and lose stickiness.

Cleaned the shoes to about 97% and he would use them from now on.

A magnetic band that is a step up from his $1 band and cheaper than Apple's.

His pick of the whole video: a simple, well-designed, toolless light that just works.

Manually tinted glasses that tint one lens at a time, and he felt misled by the ad.

Worked well, with breath smelling of nothing hours later, though the price is high and the ingredients are questionable.

A decent whiteboard but a bad wallet, since cards are hard to insert and remove.

Nicely made with a slick app, but firmly a toy.

Surprisingly comfortable, well made and left him feeling warm and alert.

Thin, discreet panels that gave about a 40% improvement to a very echoey room.

Shuffles imperfectly but deals neatly and understands the game, which impressed him.

Looks freakish but kneads firmly and feels good, so he says it would be worth it.

More a Roomba with CCTV than a relationship device; better than expected but he still wouldn't buy one.

Clever and low-power, but the image looks worse than a printed photo and costs far more.

A rebadged cheap Ukel phone with a clear interface and good support, but a weak display and a pricey subscription.

Delivers on its promise with one cable, but the screens are basic and it is too niche for him to use.
