This is a good item if you are traveling overseas…

Rating: rated 2.5 of 5 stars
Source: bought it new


  • Small size
  • Simple to use


  • rechargeable batteries with no way to replace

This is a good item if you are traveling overseas with questionable water and accessible outlets for recharge. Packing with it is another thing. I know it is solar compatible, but that is just more stuff to bring and chance breaking. I'd rather just bring my old dependable filter or tablets.
