Extremely well built flashlights. I have multiple o-lights and finally feel like I've found "the" flashlight I will use and no longer have to search for the best. I am an automotive technician and use flashlights everyday for work and after 5+ years of buying different brands and styles I'm finally happy and have no reason to try out any other lights. These lights are not only bright but the battery life is excellent, lasts me 2-3 days of use on one charge, and that's using it 8am-5pm, very small without feeling like it's going to break, durable, and best of all simple. It works with out having any extra features or buttons to get in the way, the magnetic tail cap is perfect for sticking it wherever you need so you can use both hands. I currently have 2 in rotation at work and one for home use and I have to the urge to just buy more because they are that great!!
