I think my neighbor paid under $20 for the one he gave me. He told me that you don't want to run the batteries down to dead, and I've done pretty good at avoiding that and I've used it quite a bit, so I figure it's done pretty good. The battery cover had clips that have broke, but I wrapper a rubber band around it and it works just fine.

I might go do a night hike tonight. It's sweet out right now!
