“I got one of these this year for kayaking, without really much thought of any “practical” uses for this. It works pretty well for sweeping in any event. I did find it funny with the lawn mower example, in that I was wondering how Bob is going to start the mower without using this device to lock down the safety stop when he starts the mower. (Assuming pull start.) Still better than my method of using a strap to lock it down….Thanks for the how to, in that my experience was picking this out of a catalog, putting it on, verifying it works, and then going home.” – Jennifer W.

“I just wanted to thank you all for helping me get set up with the wrist and the Multi-D. I’m working on my private pilot’s certificate and the combination works perfectly! The wrist disconnects quickly when the instructor wants to take control to demonstrate and snaps back on easily when I’m back in command. The Multi-D holds on tightly and rotates just right for full yoke movement.” – Aaron
