I have had a couple of these on two different machines. They worked great and it was easy to put the clip back into place. Although after a couple of seasons of use, the plastic clip would split right after the cord loop, eventually moving apart like two fingers move away from each other (as a scissor would open). The grounding mechanism works on spring tension separated by the clip. As a cracked clip eventually scissors open do to the sled bouncing around and coupled with spring tension on the clip, the clip comes out and the motor is grounded. I fixed it using epoxy on one and a combination of a tiny screw and epoxy on another. Also the internal spring mechanism is made of brass and corrosion builds up. This corrosion is enough for it to stick (as if the clip was still in it) and will not ground the motor when the clip comes out. It was an easy fix, just take it apart and clean it up. No matter what tether you use its a step in the right direction, just ask anyone whose sled has ran away on them or your sled is on its side, throttle stuck wide open and the track lugs whipping round and round going whop whop whop on your brand new 200.00+ jacket and actually didn't mind after all said an done because it wasn't your arm that wasn't taking the beating. I have since switched to the OEM rubber button style tethers and in the 5 years of use, I have never had a problem with them.
