*by T***G on September 27, 2024*

Received this item and was so excited to use in on my next backpacking trip. I tested it at home as you should anything before trusting it when backpacking. Seemed to work really good. It was going to be nice just being able to fill it up and just let it hang there unattended while it made my water. All was good till I accidentally threw it in the fire. smh. I'll by another one.
