I was excited to receive this wristlet / wallet & upon opening found it had some type of glue stuck to the exterior & one of the zippers gets hung up and makes it difficult to zip. I am returning & do not recommend this item for purchase.

Ex Output:
negative

Ex Input:
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 Output:
positive

Ex Input:
Finally sheets that actually fit the Cal. King and are deep enough for a pillowtop mattress. Getting 4 pillow cases was a huge benefit because when you have a king you always use at least four pillows, a practical and nice looking set of sheets

Ex Output:
positive
