When two eyes just aren't enough, its time to invest in the 3rd Eye Stroke Trainer. In the old days you had to set up a Coke bottle and practice by poking your shaft in and out of the hole. Now all you need to do is attach this trainer to the end of your cue and you'll be amazed how quickly you're stroking like a pro.

NOTE: The attachment arms come small and should be expanded by hand carefully to bend the plastic open. Trying to snap it on without pre-stretching will often cause an arm to break.
