Being that I change just about all of my riding buddies' tires, I bought one a year or two ago (it was practically free as it put an order over the minimum to get me free shipping!) I don't really have a problem just using a pair of 8" spoons, but if it was going to make changes even easier I figured why not? I tried it a time or two but really didn't see much benefit to it, the times that it could be useful it seems like grabbing a third spoon has served me well. I bet if I ever switch to bibs instead of tubes that this thing will be worth it's weight in gold.
