I've been using that strobe for about 7 months now both for marking areas, locators, safety and fun. And I think that it's a little tought piece of equipment. I mean I don't beat it up with a stick but I don't baby it either. It's getting it's share of abuse. One of the problems that I have with it is that with IR shield extended sometimes I would turn the strobe on and forget to turn it off. It will be flashing until batteries die since I can't see the IR light with naked eye so I'm assuming that I shot it down. Otherwise it's a fine peice of equipment.
