I
used to have a BM fit, but I have a fitbit now. I got rid of the BM fit because of several reasons: It's on my upper arm... everyone. EVERYONE asks what it is. After a year and a 1/2, that got old, lol. When I would work out really well, after sweating a lot, my skin would itch like CRAZY where the metal pads touched it. And, it has a monthly fee. I hated that. Paying to see what I do. Boo.
Now, for my fitbit, I love it. Its small and I can clip it to my bra strap and no one but me knows its there. I can track my calories burned, my steps, everything the BM does... and its free. There is no monthly fee.
And fitbits customer service is WAY better than BM's was, in my expierence. I had an issue with an order from BM (I ordered a new arm band and a skin for it) and after the delivery date passing, and I still hadn't even gotten my ship confirm., I called... the guy and then the gal I spoke to seemed like they were very flippant and could have been doing someting else. Left me meh. I'm a stickler for customer service, though. I had an issue with my firbit in March, and I sent an email asking about it. They responded ON St. Patricks DAY -a saturday too!- and resolved it... then it broke about a week later (software issue, I think) and they sent me a new one no charge, no questions asked. Way nicer on the phone, too.
I just like that its so much smaller and its free!
