Heart-rate and sleep tracking works pretty seamlessly. Companion phone app seems to work pretty well. Scrolling through lists of things (like the fitness activities or settings) is very finnicky.

I wish that there were more watch faces available. That's pretty awesome. Overall, my husband is very pleased. Here are several other noteworthy items.

I love how sturdy it feels, but also lightweight and not bulky. Sporty and durable.

Overall, a very sleek smart watch. Built-in function is good enough for everyday use. This is a great device if you know what you’re buying.

Tried x2 watches, menu text disappears after update when 1st set up on both such that you can't tell what you are clicking in the menus. The screen keeps coming on like a bad flashlight, even though it is on do not disturb.

The battery stops recharging one month and 3 days after you buy it! It has a mediocre battery life and at times refuses to recharge the battery. Once you plug it in, it powers on then shuts off.

The watch looks good but the functionality is far below cheaper $20 watches. There are $15 digital watches on sale at amazon that outperform this pos.
