My original Fitbit Inspire 2 worked wonderfully & IF the lil peice that latched the band in place hadn't broke while shoveling snow in January, I'd still be wearing it & it working today. I can use it on the "clip" but that only tracks steps/exercise. I wanted heartbeat, sleep & stress as well. SO, I ordered this as a replacement. I was upset because initially it didn't display when I "pinched" it & decided I needed to be more aware to "hit the right spots on both sides simultaneously. A problem I'd never encountered with my original. I purchased this in February shortly after deciding I'd rather have identical to the 1 I loved that did what I needed than a new model with extras I wouldn't use. On Wednesday 5/15, after checking my current "step count", I took it off (as I've been doing, to go mow so it doesn't count the "bouncing on the riding mower as steps) & put it in its usual "safe spot" where it goes when I'm not wearing it. Several hours later I came in, put it on n went about my evening activities. When I went to check my steps before bed, the display would not come up. I took it off & made sure I was pinching correctly & no display of any kind, not even a blink. I got the charger tho I knew it was just charged a couple days earlier & it briefly flashed a quick display then never again. I got a soft dry cloth & cleaned the back thinking maybe dead skin cells or invisible layer of body oils etc had been blocking the signals. No difference. I could, disconnect & reconnect the charger, pinch all I wanted but nothing, no display. Here I am a week later still wearing it because it counts the steps & seemingly everything else if I check in thru the app, but the display has never come back. I used the water lock whenever I was going to get my hands wet & removed it (as I'd alway done with the original) for bathing, showering etc. I really do like this Inspire 2 & other than this issue, would recommend it for the money. Unfortunately for me, 3 months of use & no working display & only able to access my stats thru the application, I'm disappointed. It's inconvenient as I also used it as my watch, so now wearing a watch as well. So my advice is try it & I hope it works for you as well as my original. I'd give my original 5 stars. This 1 based on its short display life, I can only give 2 stars to. Oh, also be aware if tracking sleep, if you're laying relaxed n quietly in bed or even your recliner, reading or watching TV, it is known to count (me anyway) as asleep tho I am very awake & watching or reading & know exactly what time I've shut everything down & settled in. (That short time it registers as awake on the chart) this existed with my original Fitbit Inspire 2 as well.
