Steripen Classic 3 UV water purifier
Steripen is easy to use as 123, it is compact but not water proof so don't leave it in the rain or drop it in your water source. It works very well as advertised. Very nice to have and use with confidence. Must use in clear water to kill bacteria and viruses. Thanks Knife Center.
