Review on QIBOX Sports Silicone Replacement Bands For Charge 4/3 - Breathable And Comfortable With Adjustable Sizes For Men And Women by Ryan Foles

Looks great, love the single snap and the tuck under of the remaining band. My only issue is the sizing. I originally bought a large and felt it was a little too large, as the end of the band (the part that tucks back under after it is snapped) almost got all the back to the FitBit itself. It worked fine, I just wanted it a little shorter. I then bought a small one thinking it would be better and it would not fit at all. They really need to either come up with a medium size, or maybe make the small a little larger. If you have an average to large wrist, the large should be fine. And if you have a smaller than average (but not really small) wrist, you may still need the large. It says the small will fit a 7.5" wrist, not a chance. 7" tops.
