Pros: Durability, Bulb Durability
Excellent UV light
I originally bought this flashlight to check glassware from the 1890's to see if they were authentic. To my surprise, the light can spot all kinds of stuff! -Checking American Brilliant Cut Glass for authenticity -Seeing if minerals fluoresce -debris on the carpet, especially where Jack wee-wee'ed (our dog) The case is tough and rather thick as you can feel the weight of it. The on off momentary button is sturdy. When you press the button you can tell that it was well designed. The LED's are recessed so they won't get damaged. As for durability and etc...I haven't owned it long enough but it sure is sturdy. Don't expect the lights to shine across the room as it's not that kind of light. You have to be in a dark place to really appreciate how well it works. The "Pro's" that I marked are based on how I think it will perform over time.
