The stuff goes on the thing and it doesn’t fall off. What more were you looking for? Bike finish stays unmarred and the tube is firmly attached after many laps.

This is the best tube strap on the market, period, end of story. I own too many MTBs and have one of these straps on each of them. They are constructed of super durable material that will probably last longer than me. From experience I can attest it is durable enough to survive unwanted encounters with your rear tire should the two meet whilst your dropper is slammed. Plenty of room to fit a 29er tube and levers, and probably even 2 tubes if you wanted. Just buy it...
