Hi Danny, I'm still making prototypes of the glide-locks. After each one I think of something to improve and then I go through the process again with a variation. This is what happened with the PalmControls. There were like 14 prototype variations before releasing the PalmControl. Although, I'm sure (I hope anyway) I'll run out of ideas long before version 14 of the glide-locks.
There is a more basic version in the works that should be released soon though and they will work smooth.
