This is an excellent edc light that would be a great choice for someone looking for an affordable very bright and reliable light, but also a great choice for the flashlight enthusiast. The user interface is very straightforward for the basic functions, but it is also packed full of features that you normally only get with full custom drivers. They provide a good quality battery and the build quality on the aluminum is excellent. The electronic clicky is smooth and the threads holding the head are machined with precision. The o rings seem to be of good quality, so I'm sure the ipx rating is accurate. The color is nice and uniform and I'm a big fan of the slate gray look. Not too much sheen but not a matte finish either. Only time will tell how it will hold up to regular wear and tear.
