[Q]: The bands work great and I like the different colors which make the Fitbit more versatile. I wear my Fitbit all the time so I am able to change the band to coordinate with what I am wearing. Great price and made very well. I have had mine for about 2 months now and have had no problems. Received the item in a timely manner!!
[A]: positive

[Q]: Unfortunately they didn't work for me at all for they doesn't work with soft tissue. My skin tissue is too soft and it won't stay in place. So be careful unfortunately it won't work for everyone. The firmer your skin is the better it may work.
[A]: negative
