Bests & Worsts Reviews from Amazon

I work out all the time, and I wear my Fitbit all the time, regularly participating in competitions with my friends. The motivational part of the Fitbit gets it one star. Here's where the stars start falling off. While I love the motivational aspect of the Fitbit and love a little healthy competition with my friends, the stats are not very accurate. Having had a polar heart monitor (strap included) before, I knew what my heart rate and calorie count should be, and the Fitbit is pretty far off-base (1 star down). Also,I purchased this in 2015, and right around a year later, the area on the back where you charge it completely fell apart and looked completely corroded inside (aren't these supposed to be sweat resistant...especially since they are typically worn by people working out?) - two stars down. I might also add that I regularly made sure I took it off and let it dry completely before putting it back on. I contacted Fitbit, as I had heard their customer service was great. They reluctantly gave me a new one, but made sure to let me know that it would never happen again - three stars down. There's no sense in being catty. It wasn't like I didn't have a legitimate complaint. It's my feeling that if you know people are going to be wearing these almost 24/7 AND sweating in them, they need to be more durable. Less than 6 months into my SECOND Fitbit, the back has again fallen apart (you can see the crack in the picture where the charger connects to the tracker) - four stars down. I'm done. I'm very careful with my Fitbit. I was even more careful the second time around to make sure I pressed against the back as I was pulling the charger off, and it still fell apart in even less time. I'm going back to my tried and true Polar.
