I conducted quite a bit of research on rail mounted tactical lights ranging from Surefire to Insight prior to this purchase. Besides the price, one of the things that made me decide on the Streamlight were the many positive reviews. Most of the time I don't put much stock in internet reviews because they are not always accurate. However, in this instance I chose to believe in the hype and upon receipt of the product I was not disappointed.
The one and only negative to this product are the poorly written installation instruction. However, this was easily remedied by hitting the internet and viewing a couple of videos. Once installed on my full size Beretta 90-Two 9 mm, I could not be happier. This light really puts out some lumens. It is extremely bright. The ambedexrious switch for either constant or intermittent beam moves easily with a flick of the index finger.
This product is equal to any that are twice as much and I would highly recommend.
Pros: Extremely bright for the price
Cons: Instructions for set-up are not the best
