Wearables

It does make me feel more comfortable, but the effect on overall body temperature is small for now.

A dad watch with unbeatable utility and battery life, but I wouldn't switch to it.

It gave the highest calorie figure at 2,393, and I singled it out as the least trustworthy of the four.

A strong upgrade with a faster chip that fixes the lag, a bigger battery and useful new health features.

Actually deserves the Ultra name, with a 35% bigger battery and a 5,000-nit display, though the brightness is excessive for most uses.

Its calorie tracking and instant Apple Health syncing are accurate enough to be useful, which no Android watch matched for me.

Overstates calories compared with the Apple Watch and syncs unreliably with the Oppo, so it did not work out.

Dismissed because the user interface is laggy and unpolished.

Ruled out because almost nobody uses it, so third-party fitness app and gym support is doubtful.

Not bad, but it gives too much information and none of the smartwatch perks, so it wasn't for me.

Claimed as designed in India, but appears to be a Chinese AI Power product co-developed with that firm.

Reported 1,377 calories burned, far higher than Apple and Samsung.

It woke me up quickly in the morning but never improved my sleep, so I stopped using them.

App-guided breathing trainer that gave noticeable lung strength results and was easy to use.

A mouth-worn breathing restrictor and tracker that I call clever, and I plan to use it to boost my VO2 max.

A tiny, readable Casio watch with full functions that I really admire, though I'm not sure if it's a joke product.

Nails the retro-future look and uses good materials, but lacks a backlight and is hard to wear, so it gets a C tier.

Nice but strange to pay twice the price for materials on a value-focused product.

A far more capable smartwatch than the Smart Band 10, but with much shorter battery life and less comfort for sleep.

An affordable smart rope that counts reps fairly accurately and works cordless without the app.

A $45 band that rivals the Apple Watch Ultra 3 for health tracking and gets 10 out of 10, plus the Hall of Fame.

Weighty and luxurious in feel, but the low-resolution display and unreliable crown make it disappointing at $4,300.

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

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.
