Has a few issues - LaserLyte LTS Universal Pistol Trainer Laser LT-PRO

First, the batteries must be removed each time after using or battery life will be less than two days. Must unscrew unit and remove top to "Turn off" and stop battery depletion. Hence, one must remove unit from weapon after each use, unscrew top of laser unit.

Alignment might be required after setup. Sometimes the aim is off, so the laser unit must be removed and re-inserted to get good sighting. And since unit must be removed from pistol after each use to preserve battery life, definitely not as convenient as could be. Still workable. Just takes a little time
Pros: When set up, will provide good training
Cons: Battery life, Must be set up to aim accurately
