I have a MAP that I really liked, love the concept. It had some QC issues that I was able to take care of (stuck set screw, loose set screw, etc). I had an issue where the arrow was sitting correctly when nocked but at full draw the magnet was too powerful and pushed the arrow up so it was sitting in a little valley between the wire and the top of the button. Easy to adjust so that won't happen but something to watch out for. Again, I love the concept but my opinion is there are too many screws that could loosen, along with the QC issues I mentioned, so I switched to a Zniper. I suggest waiting for the new version or get a Bi-Drop, which I plan on picking up.
