I tested every Celebrity Tech product!

A smartwatch that depends on a server that appears to be down, so it barely works.

A face mask packed with features that fails at the basic job of sealing around the face.

Earphones designed to look like vinyl records on show in your ears; he gave will.i.am a three overall, mostly for effort.

Not professional gear, but a fun toy that makes even bad singing sound passable; scored 5 out of 10.

A pretty standard e-scooter that is fun to ride but has few standout features; scored 6 out of 10.

A rebadged Android handheld with broken controls, a poor screen and an AI that crashed; scored zero.

A generic, soulless speaker that is poor value at $130; scored 4 out of 10.

A fascinating AI stem-splitting toy with poor sound and awkward music loading; scored 5 out of 10.

A cheaply made popcorn machine that smoked and covered itself in butter; scored 2 out of 10.

Addictively good scents and clever design, though it runs through fragrance quickly; scored a high 8.

Mediocre earbuds with an ugly purple finish and sound profiles that barely differ; scored 4 out of 10.

A powerful, decent speaker with a bass control that just tweaks software; scored 6 out of 10.

Easily the best sounding product in the video, helped by Kim picking a good partner; scored a 6.

Baseline earphones priced at $130-140 with misleading marketing; scored 2 out of 10.
