Even though I don't feel comfortable relying on moving parts, or electronics and batteries in this case, the size and capabilities of the Steripen --and a wholesale price-- won me over...hesitantly.
I ended up with the Steripen Adventurer 3 yrs ago. I have used it on three trips. The first two were trouble free. The last trip however, the thing had to tried repeatedly before it worked. Total, I have five days on this thing. Original batteries. All these trips were short totaling 3 nights. It could be the batteries....but the indicator light did not indicate a battery issue. What ever the case, I'm now even more hesitant to use it. My brother has a newer version he took to Mexico last winter. First trip and it completely stopped working. No indication it was the batteries in his either.
To be fair, it could be a simple battery problem in both. I can't speak for my brother but I'll have to think long and hard before I take mine in a remote area again. Fresh batteries or not, I'd feel like I was in Nevada at a gambling machine every time I pushed the button.
