I hear ya. For the money it was a quick fix, and I didn’t see any “I wrecked because of GripPuppies” reports anywhere. I have a CrampBuster somewhere and it never really helped me. I think it’s the combination of the rpm buzz/vibration and the grip OD. I’ll go numb fast. The larger OD on my retro grips*helped, and these feel about the same without changing out the OEM.
