Laser Putter attachment

Saw this one dollar laser at a dollar store and thought it would be fun to have a laser sight on my putter. Might even end up being the perfect fathers day present. =) My favorite part is the "switch". When you twist the laser to the right the button does not fit and is pressed. I left a gap where the second button is (led light) and it works like a champ. Just need to head to the course to give it a real test.
