Inspire 2

I have a used Inspire 2 and I love mine too :)

My inspire 2 is the best Fitbit I’ve had with which I’ve swam a few times and it has best water-lock feature I’ve personally experienced. You can press both sides any time (even and especially useful AFTER starting a workout) to engage it with. I couldn’t speak for your specific needs though as I basically just swam and didn’t check what it logged. I’ve had charges 4 and 5 and sent the inspire 3 back because it lacked this key feature which is essential for me.

Mine too! And the battery lasts like two weeks before I need to charge it

The Fitbit Inspire 2 is like $10-20 on eBay these days, depending on what sort of condition you want (I'm going to scuff the thing no matter what, so I have low standards 😝). It's a seriously great little device. It's unobtrusive and waterproof, the battery lasts forever, it tracks heart rate and sleep in addition to steps, and offers nice little movement reminders if you so desire.  For *my* bouncy gait, the step tracking has been accurate in every test I've done, even when pushing a cart or stroller. My wife's experience is different: She tends to glide rather than walk, and sees more undercounting than I do. 

I agree about the Inspire 3. I've had mine for several years and use many of its features every day. I think it tracks steps better than any of my husband's Charge models (3,5,6). I liked my Inspire 2 and bought the 3 only because I could swim with it. I gave my Inspire 2 to a friend and she is still using it.

I had an apple watch and switch to a fitbit inspire 2 a year ago and couldn't be happier. Doesn't have the bells and whistles but it tracks all of the important stuff.

I am very happy with my cheap inspire 2, especially as I wouldn’t necessarily want to put a ton of money into a new Fitbit with the uncertainty around how much longer Google will keep it a usable product. I use the stats heavy home screen option and it has all the information I care about without scrolling or hardly ever opening the app. Just a band I charge every two weeks. I use the default band but there’s some very nice aftermarket options out there.
