The laser is VERY bright! Which is great but could also be bad... I wanted the bright green laser and it works awesome. Just so you know, the laser is so bright you can see the entire ray from barrel to target, it reflects off many surfaces (sometimes in multiple directions although not too distracting), and in a completely dark house the laser can actually light up an entire small room! So the green works great, but I could imagine situations where it is too bright...
The attachment rings are nice too. Because of their small size you have many options of where/how to install the laser. The inside of the rings are "padded" to protect the metal parts. The only complaint I may have is that it isn't easy to adjust the precision of the laser on target compared to the barrel... but I guess it doesn't have to be perfect considering some situations...
The wire leading to the push button is strong and good. I like the option of using the push button power on, or an on/off power switch. But the velcro and the sticky to attach the velcro to your weapon is very weak! I had to use superglue on the sticky and velcro to keep them both in place!
I found this product VERY expensive, especially considering most of the price seems to be because of the laser's color. But it has all the options I wanted (green laser, small attachment rings, push button) so I bought it anyway... I am happy with my purchase. Really, the laser should last a long time (it is solidly built) so the price isn't so bad in the long run and compared to other laser sights! That was my justification.
Pros: Bright green laser, variety/easy installation, can use on/off button or wired push button
Cons: PRICE, velcro/sticky for push button sucks.
