Review on Extender Band for Fitbit Wristbands - Perfect Fit for Larger Wrists or Ankle Wear, with Buckle Closure by Rebecca Massey

actually bought by mistake. I was looking for an extension cord for the Alta HR and it was for the HR charger which has a longer range so I couldn't use it. I would have sent it back if it wasn't my fault and unfortunately shipping almost cost me the product. Seems to be good quality for those with a Fitbit Charge/Charge HR to extend the length of the strap. I don't know why but for the Alta and Alta HR they stopped selling XL straps and the large straps usually barely fit my very large wrist. But I happened to find some extra long sports tape, so I'm happy. Can't give more than 3 stars as I've never had to use it to see if the form, fit, functionality and feel are ok. If I had used it, it might have received a higher rating.
