## Customer Reviews

### ⭐⭐⭐⭐⭐ Amazing water filter straws – great for hiking and emergency kits
*by S***  on July 14, 2025*

I originally bought these water filter straws for my emergency kit, but I had the chance to try them during a recent hiking trip and I loved them. We tested them with lake water and it worked perfectly—the water came out clean with no weird taste. I was really impressed with how well they work and how easy they are to carry. Now I feel even more confident keeping them as a key part of my emergency supplies.

### ⭐⭐⭐⭐⭐ Great idea
*by K***. on August 14, 2025*

I have read about these straws and hope to never have to use it. I bought it for an emergency situation.

### ⭐⭐⭐⭐⭐ Good price and well built
*by S***R on September 4, 2025*

I bought these because of a recommendation. I have not used them as of yet. They appear to be made well and come with a good rating from other customers. They are portable with a fair price point and can last over extended use.
