This has been a life saver at many gigs. I don't drop sticks often, but it's like the seat-belt of the gigging drummer. can be a bother putting on and off all the time, but when something goes wrong you'll be glad of it!
I have found with this one it doesn't tighten as much as I'd like to, it stays the very best, but I can still push it down if I lean or hit it.
This also acts as a cow bell (kinda) when it runs out of sticks!
