My Garmin strap is starting to show a lot of wear (I've had this one for a few years and it's been through the washing machine many times). I'll probably look to Wahoo for a replacement - I'm intrigued by these wrist/arm straps. My Fitbit isn't very accurate but I think it's because I keep it too loose on my wrist. Something with a fabric strap probably works better than a watch in this regard.
