Things I liked:The rotary switch lets you switch from laser to laser and light then to light, that's behind the flashlight and before the mount. There's a toggle switch in the back, its slpit. one on the left and right side, this allows you to switch from momentary, permanent, and off position, thats easy to use. Both toggles do the same job. The light is very bright and concentrated in the center.The laser is very bright and good in the daylight for 40 feet. The mount fits solidly on weaver mounts. The all aluminum construction is strong. Two CL 123 batteries slide in under the mount and they go in easy.The clamp that holds them in is strong and will last. The unit fits well on a Crosman T4 with room to spare. the unit is 3.5 inches, most of that length is in the front. there's a button swicth on the back of the laser, this also turns the unit on and off. Nice so you dont have to toggle all the time. Great value for the money! Things I would have changed:Make tha adjusting screws for the laser stiffer, I think after awhile it may be moving a bit. What others should know:I will tell my friends about this unit.
Things I liked: The case is made good, but there was a hole on the back and right in the middle of it. The sliding locks are really nice. Things I would have changed: The foam is not dense enough. What others should know: Look at the demensions of the case before you consider buying it. I've got a crosman T4 and it just fits.
