[EX 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!!
[EX A]: positive

[EX Q]: 4.5 stars The vented bottles helped so much with my baby’s gas problems. Took half star off cuz they are diff prices depending on color, wished they were same prices
[EX A]: positive
