[EX Q]: I absolutely like it The brain booster influences well on my alertness and memory. I feel much more clear after half an hour of taking them. I think that they even improve my critical thinking.
[EX A]: positive

[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]: Great product for the price. Fits perfectly and each brush comes with a hard plastic cover. Included are also a couple of color rings in case you have few family members with the same brush.
[EX A]:
positive
