" ... The strap is really hard to close. ... It's hard to get it into the charger and next to impossible to figure out how to get it back into the strap. ... "
" ... Wrist band broke after 2 days. ... "
" ... Have since gone to a buckle band because this is difficult to latch, and often falls off. ... "

" ... My wrists are tiny, but this band was way too tight for my wrist. ... "
" ... It has fallen off a couple of times but luckily I found it. ... "
" ... The strap is really hard to close. ... "
" ... The large wrist band is too large. ... While the small one is kinda tight. ... "
" ... Had this one two weeks and today while out walking, it fell off. ... Doing so did not work as I was constantly having to re-pinch the clasp to hold. ... "
" ... I couldn't get it fastened on my wrist, and once I did get someone else to help me, it was hard getting it off. ... I suppose it worked ok, but not if I could not wear it. ... "
" ... -Putting this thing on is a hassle and you actually have to dig those two metal barbs into your wrist so that they poke through the other side of the band. ... I really do want to like this product, but it's difficult at times to feel like something which has been on the market for at least 3.5 years before I bought it could perform this poorly and still receive such high praise. ... "
" ... The strap does not work worth a darn. ... "

" ... I can track my steps which is encouraging to see how far I've walked throughout the day. ... And it encourages me to walk more to reach my goals! ... "
" ... Pretty good tracker for the price of it. ... "
" ... I loved being able to count my steps when I worked a job with a lot of moving about. ... It gave me a sense of accomplishment and motivated me to exercise. ... "
" ... -Counts steps well ... I guess the total amount of steps is accurate since the previous sync, but that's not the point. ... This personally matters to me, because my workplace requires us to walk a certain number of steps per day in order to maintain "lower" health insurance rates (lol). ... "
" ... Helps me want to get my steps. ... "
" ... I don't need all the bells and whistles, just the steps. ... I showed him the program on my phone and we counted out steps together, so he could see the number change. ... "
