Great so far!!
So far this has been great! the bracelet is difficult to push into place, but its nice to have two different size bracelets to choose from. other reviews have said you can only have one fitbit device connected at a time, this is true i have a one but have not used it (im giving it to my brother) so replacing it with the flex was fine for me. the instructions that come with it are simple, open device, slip it out of bracelet, charge it, once at least 3 lights show it's charged, then put it back in bracelet, put it on, you really have to push, then follow directions on the fitbit app and boom you ready to go. i really like the alarm, works great! i haven't had this long but i'm very pleased. i'm going to order the other band colors too!! very much recommended to everyone but especially to first time fitbit buyers!!
