Things I liked: Windage and elevation adjustments - many other laser sights don't have adjustments and are for big people-sized targets i guess. The easy way to adjust was to clamp the gun, shoot a hole in a target, then while the gun is still clamped aim the laser at the hole... then shoot another check shot. Attached mine to a Crosman 1088 bottom rail with no problems. Nicely made.
Things I would have changed: could break the sharp edges a bit, laser danger lable is covered up in use. Momentary button on rear limits how close to trigger guard you an mount it.
What others should know: states comes with 6 button cells but only uses 3 at a time, other 3 are spares, but one of mine was basically exlpoded and bad. But they are standard LR44s you can get fairly cheap at hobby stores, dollar stores.
Things I liked: Good heft, feel
Things I would have changed: Hard to cock. Major chance of getting pinched, particularly after you cock it a few times and you get a little tired. Hurts a lot when you get pinched.
