I wear mine on my right wrist, it's hooked to itself to make a loop and I put it on and pull it tight it has never come off my hand. I never ride without it but I am guilty of starting the sled without it on. I am in the habit of squeezing the throttle before I start to make sure it is free and not frozen but it I should put that thing on before I start it. Was on the trail in Revy helping a guy out of the trees and a few people stopped to help. A mod sled behind me started up and it took off with the guy standing beside it, glanced off the back of my sled and nearly hit me in the legs, luckily the guy had his tether on and there was no damage done. I don't even want to think about how hard it would have hit if it would have been still running.
