I've got one of those too. Picked it up a few years ago. I think I got it at Target on sale for around $8 at the time. It does a decent job for the money, as it has a pretty nice floody "beam". I have put quite a few hours on it without any problems.
To keep the switch from getting accidentally pressed into the "on" position while in storage (and it happens everytime), I cut a small piece of plastic off of the plastic blister packaging, and slip that in between the batteries and last + contact. Just a quick little trick to save your batteries. When I get the light out to use it, I remove the plastic shim and leave it floating around loose inside of the light. Can't lose it that way. :D
I still have my nice little LED lanterns we all use too, but this light is nice because since it stays in the tent it is always there. I like the flat, round shape of it as it packs nicely into the end of my tent's stuff sack.
