Everyone in my family has a Fitbit Flex and we like to wear them when we travel too. We are always paranoid about one breaking or loosing them and then having to buy one from Fitbit (which is around 20$+ for one charger). However, this comes with TWO for way cheaper. I thought they may not be "compatible" like some chargers that aren't "name-brand" are, but these worked great!! They charge fast and work just as well (if not better) than the original. They look almost the exact same too (this one has a slightly longer cord than the original...which is a good change), and the Fitbit fits right inside just like with the original. This product is as described, and I would highly recommend this!
