Everything I've tested.

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.

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.

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

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

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

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

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

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

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

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

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.

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

Most futuristic jacket he has seen, and he would almost definitely buy one for travel once it is released.

Impressive and the most discreet execution of a powered exoskeleton idea he has tried, but not mind-blowing and unclear who it is for.

The pair that blew him away; addictive massaging nodes let you feel the ground, and the sneaker version works better than the slider.

Clothing he expected to gloss over but found really interesting, with sport-specific airflow that he could feel while sprinting.

The slider version of the Mind concept, which he found underwhelming compared with the sneaker.

Looks lovely, but the symmetrical shape is awkward and the Logitech is the logical choice.

The maglev stand is impressive, but the price goes into a gold nib and the build feels not premium enough.

Great unboxing and a titanium body, but the watch faces are odd and it offers little over the normal Series 11 for four times the price.

Beautiful with a charming dial, but slow and low capacity, so he would not carry it even at the same price.
