I love this clip. I wouldn't be without one. Using it the educator controller is always on hand. I can draw to it at any time like a pistol and hit the button immediately. This keeps the timing of the stimulus exact. No more fumbling for the controller and delay of the handler's response. Timing is everything. I gave less than 5 stars because my first clip broke. The spring was bent somehow so that it is unusable. I don't know how it happened. But...I'm buying another one. Must have.

Very handy clip and very fast delivery I highly recommend it.
