Strange gadgets

A convincing fake with working hole punch and Note-style software, but the front camera is quite bad.

Wildly cool true wireless charging concept, but power drops off quickly as the phone moves away.

Tiny transmitter that sounds lame at 100 milliwatts, but he is confident the technology will improve.

A connected Rubik's Cube with an app that adds guidance and minigames, and a very smooth feel.

A sensor kit for playing drums on any surface that he found mind-blowing, though it does not fully match a real kit.

A weightless workout tool that turns resistance exercise into phone games, which helps distract from the pain.

A backpack with a pixel display on the back that is a fun toy, but needs a power bank and offers little real benefit.

An umbrella with a battery, USB port, solar panels and a fan, which he calls possibly the world's most advanced.

A small fan with sticky pads that packs a punch but has a pointless LED.

A handheld printer that prints on almost any surface, limited to one colour and horizontal content.

A cheap, cheerful and surprisingly bright disco light that does the job if you want a small rave.

An expensive water-resistant suitcase whose interior acts as the sound chamber for a built-in Bluetooth speaker.

Became his favourite item in the video, a clip-on tap attachment that reduces water use and stops with a hand wave.

A really weird AR t-shirt that shows your insides through an app, a cool learning tool as well as a toy.

A strange rear touchpad that feels like reaching through the phone to touch the screen.

An unusual tiny printer you swipe across paper, though tall images were hard to get right.

One of the coolest things on the list, letting you hear through walls.

Cool to see but not something he'd recommend, and electromagnets are bad for phones.

A charming, pet-like robot that feels alive, though the entertainment is thin for now and battery life is unremarkable; this was a sponsore…

Last year's Anki robot, which Vector succeeds and has more potential than.

He hates how it looks but it is the softest, most comfortable case he has held, though it barely fits a pocket.

He cannot understand the thinking behind the grass case, though it will make you stand out.

A cleaning-fluid-bottle case he calls dumb and pointless, though eye-catching.

A heavy, uncomfortable chunk of silicone shaped like an ear that he finds ridiculous.
