Review on 4PCS Fitbit Flex Band: Silicone Replacement Wristbands with Metal Watch Band Buckle - Large/Small - Sport Bands for Fitbit Flex Bracelet by Jathan Louis

These straps are slightly wider than the original factory straps from my Fitbit brand, but they are also stronger and will not fall off due to the different clasp. Definitely a bit more voluminous, but safer. I liked the different colors and wear my Fitbit more regularly now as I'm not afraid of losing it. I bought a pack of five original Fitbit straps from REI last year, but the latch offered isn't as secure as it is here. I've attached side by side photos comparing the slightly larger straps I got from Revain to the Fitbit brand straps I got from REI.
