I could right an entire book on my love for the lights of Pentagonlight but I will try to keep it short and sweet. They are essentially the Surefire for the Average Joe that is actually as good or better in some cases than similar Surefire models.
I run Pentagonlights on my rifles for varmint/hog huntin' and usually EDC 1 or 2 models on any given week and I will say they are excellent lights from an excellent company.
I currently own 6-7 of their lights and acutually have all the models except the one shown in the original post and have had no complaints. I have had to deal with their customer service 2-3 times and each time I was satisfied and taken care of quickly and professionally. They also give out some hot freebies.
(It's a olive T-shirt that glows in the dark, they also included some GID pens, some GID quarter tubes, one of their catalogs and some other stuff. Hot.)
Let us know how you like your light when you get it!
