Good light, except one thing.
The light works well, is easily adaptable to a rail system, and has good brightness and focus capabilities. The battery seems to hold up well. The only downside I have found is that the push button on/off has no position index so there is no way of telling if the light is powered on or not. Except to look at it through an IR scope which is quite inconvenient.
