Review: Works great! - We bought this pen to use on a trip to Colombia. We filled our bottles with tap water then simply stir the pen until the light goes off and drink safely. Very easy to use. It does not leave any smell or taste from the device. Good purchase if you travel or backpack.
Review: This is my magic wand for water purification. - I have tried so many other methods -- the pumps, the chemicals, the squeeze bag -- and this is by-far my fave. I used an earlier model for about a decade before it broke and only had to replace the batteries once. This model is even better -- it's easier to see the sterilizing lights, so easier to know that it's working and when it's done. I recommend this for camping, and I recommend it for international travel. Way better to purify the tap water than to buy endless supplies of plastic bottles.

### ⭐⭐⭐⭐⭐ Making sure I don't get ill
*by D***R on November 13, 2024*

I added this to my filtering system - I do a lot of hiking in the high peaks in the Adirondacks. Recently I did a solo backpacking trip - and camped out for 2 nights. I wanted to make sure there would be no reason I would fall prey to some kind of parasite from a brook or stream. I coupled this with another filtering system and really felt this to be a great solution. It was compact and simple to use. I will be using this for a lot of trips ahead. Great solution!
