This super-popular wearable is new, improved — and flawed

The useful part

I received my Fitbit Air near launch day back in May, and I've had it on my wrist ever since. In our original hands-on coverage, I loved it for its lightweight design, long battery life, and 24/7 wearability, despite a lack of GPS tracking for runs, questions around data privacy, and an inconsistently reliable AI coach. Three months later, I have more thoughts on how Fitbit Air has aged and whether or not I still recommend the device.

How it works

• Unlike larger fitness bands or even watches, its bracelet-like design makes it easy to wear in tandem with jewelry or accessories on the other wrist.
• Considering that the Fitbit Air samples heart rate data every five seconds, this kind of battery life cannot be overstated.
• For starters, the size and weight have proven to be a huge selling point for the Fitbit Air.
• Its covert aesthetic is further complemented by reliably impressive battery life that lasts slightly more than a week per charge, though this window may shorten a bit if you're a real exercise fanatic.
• I rarely have to take it off or acknowledge it's there, which is the best thing you could ask for in a dedicated fitness tracker.

Details worth keeping

I find that it's an inconsistent health partner. It's so light and unobtrusive, I forget I have it on most of the time.
