Things I liked: Compact design leaves many options open for placement. Laser works perfectly, but beware this this will destroy batteries if left on for an extended period.
Things I would have changed: Flashlight is pretty weak on the lumens side. Also, these don't seem like they could take much abuse at all in the field.
What others should know: the velcro stick pads will not stick to the gun. I found adding a locktite glue solved that problem. I added this to the evanix sniper .50 cal. The best placement for these pads also makes it an unideal location when being placed in a case because the cushion will apply enough pressure to turn the light and laser on. Make sure to remove those pads when storing your air gun.
Things I liked: Good optics. Flashlight is very bright, uses two CR batteries. Red laser dot is easy to sight/align, and won't move even under recoil of CO2 pistol. Rotating the laser around the flashlight has 16 settings, for various mounting applications. Mounting to weaver rail is also a cinch. Cheapest combo optics in the market. Separately, these two will cost about $75-80 easy. Overall a very good product.
Things I would have changed: Maybe the length of the flashlight? But it uses two batteries so the length cannot be compromised.
What others should know: Although I mounted this under a 1911 pistol, the long flashlight might be more suitable for rifles. I'm thinking this will be perfect in front of the vertical grip mounted under the rifle's RIS.
Things I liked: The build quality (i.e. materials used) seem to be very high quality. It has a sturdy, heavy feel to it.
Things I would have changed: Improve whatever electrical issue it has (see the other review regarding a similar issue, where the person was able to fix it himself). The flashlight part broke after 5 minutes of use. It could be a very minor problem, but who's to say? Also, some more detailed instructions on how to calibrate the laser would be helpful.
