I have the lazerlyte target, the 9mm insert, and the adjustable insert, and the blue gun for that insert.
I use them a lot for practicing, but eventually ended up mostly using th 9mm special cap most of the time.
The lazerlyte target is very finiky and stops working when it gets a bit cold. Each time when I am about to return it, it starts working again.
The adjustable insert lazer goes into the muzzle and works acoustically. Because of that, you have to take out the batteries every time you are done with it, because it continuously listens to the sound.
The 9mm goes into the chamber, so it acts like a snap cap too. Onver time, you can see where the lazer hit, so you don't really need the target. I use it to shoot light switches, curtain rods, cats and dogs
and various swinging objects.

In retrospect everything else was a waste of money. Last time I put the batteries back into the adjustable trainer, it did not even come on.
