If your arrows are cut to the perfect length, if you don't creep when youhave a steep anglefrom a tree stand, if you don't pull hard into the back wall, if you have time to wait for the arrow to stop moving around and settle in the middle of the magnets, ........... In other words if everything is perfect it will work well.
From everything that I have read about it...bigbulls has hit it on the mark! Neat idea...just too many little things could happen...
