Review: Junk. - Does not work. New batteries 2 sets. Turns on 2min later it’s off again. Turn on again back off. I sure hope I’m not in h2s situation with this I’d be dead.
Review: No belt clip - Thankfully, I don't know if it works or not. That's a good thing. However, there's no belt clip. I had to cut the clip off an old neoprene IWB holster and gorilla glue it to the back of this to have a clip. Of course that means I can never change the batteries, but let's face it, if you're buying this is because you're starting a job in the oil and gas industry and you're low on cash. The way I look at it, by the time the batteries die, I can afford a more expensive model (with a belt clip).
