I've never used them, however, have seen people shooting at local ranges with them. Usually what I see is the dot dancing around the target until the shooter jerks the trigger. The end result is a target that looks like they used birdshot at 50 yards. My guess is they focus completely on the dot and drive themselves nuts trying to chase it. Most would be better off spending the money on some instruction and a pellet pistol or .22 to learn sight alignment/sight picture/trigger control.
All that said, I am sure that in some circumstances they would be useful.
