Bought several- giving as gifts

I have used the battery operated version of Steri Pen for several years while hiking- works great. I like the idea of this unit not requiring batteries. You do have to crank it fairly fast- if you're too slow, the red light blinks. When 90 seconds is up, green light comes on and you're good to go. I did not find the cranking tension too hard. Easy to use and glad I got it. Giving several as gifts this year.
