I received the throttle Lock from Tom, read the instructions and watch the video before install, and didn't play with the star wheel before installing it. When I inserted the piece into the tube, it was quite snug, unfortunately though the rubber outer piece was not stuck in place well, it moved around on the metal. The original adhesive was probably just gummy. I spoke with Tom and he told me just to superglue it, I did, problem resolved. I did the card spacing, and it took many a click to get the tension good, probably a full rotation. When I went for a ride to fine tune it, it creeped very badly. I could set it, and after a few on/off engagements, I would have to adjust the star wheel again. Came back spoke with Tom again, and he advised me to narrow the gap since I don't have heated grips. Played with it for a while getting the spacing just right, went for another ride that night, and it seemed solid, no creep. I have been riding everyday this week playing with it, and its hit or miss to whether it creeps or not. Sometimes I can lock it and its locked, other times it creeps a bit.
Just my experience, but I will say that the machining is very nice, its a unique and ergonomic design, and Tom is a heck of a guy to deal with. I ordered it on a Thursday, it arrived on Saturday, and he returned my call over the weekend.
