I bought a set of tires recently and they popped up a special deal to buy a Laser alignment tool at a decent discount. So I bit on it. I like it a lot. You can aim it all the way up to the countershaft. Much more accurate than the MotionPro stick. Like the difference between pistol sights and Crimson Trace laser grips. It is smaller and easier to carry on the bike than the MotionPro stick. Takes two LR44 batteries which will surely go out right when you need it to work. I will keep the MotionPro as backup.
