That is, until the last 6 months, when a bubbling issue in the band crept up. My fault for not immediately contacting Fitbit about it, but my 1 year warranty lapsed before I could contact them for a replacement. Now I know from the forums that it is a known, repeatable issue. What I didn't know is that the bubbling would later become catastrophic for the device. I figured I could live with it.
The band itself is attached to the tracker plastic, maybe with an adhesive. The band is a rubber material that will expand gradually over time, with heat and exposure to daily use. Thus, the bubbling is an inevitable occurrence. Bad design choice.
A few weeks ago, the band had release almost entirely, revealing a slightly cracked plastic interior body of the tracker. Bad. Weirdly, I did not see any adhesive or cohesive failure on the widest part of the band, where more glue would have definitely helped. Bad. Then, last week, the last vestige of connection between the band and tracker gave up. Again, no obvious adhesive/cohesive failure from epoxy. Did Fitbit just press the band to the tracker together thinking this would work and last?
Looking at the Charge 2, I see similar design and would definitely not pick one up. Would not recommend.
Initially, I'd give this 4/5 stars for the community and software integration, but with these hardware issues, I'd have to say, 1/5 because reliability and longevity have to be considerations for an item >$100. This thing didn't even last as long as a phone.
