## Customer Reviews

### ⭐⭐⭐⭐⭐ Work wonderfully and perfect size !
*by S***A on August 29, 2025*

These are perfect size for a shorter run! Easy to hold and easy to use mid run !

### ⭐⭐⭐⭐⭐ My running era😉
*by E***E on May 13, 2025*

This is the perfect size for a simple run. I used it on my 3 mile run and it was just the right about of water. Fit perfectly into my running vest. No leaks no smell or taste. Just a quick wash/rinse after every run n let dry should keep it lasting for some time.

### ⭐⭐⭐⭐ Works well but gives water a plastic-like taste
*by O***N on February 3, 2025*

I’m only on my second refill (threw the first one out) and though the plastic taste seems to be less than it was on the first fill, it is still noticeable. Perhaps it will further dissipate with more refills, if it doesn’t I will not continue to use it. I’m not a hiker or really much of an outdoorsman, I use it to keep by the bed at night when I wake up with dry mouth. Very convenient and doesn’t spill or drip. The bite valve works great. If the plastic taste doesn’t go away after several fillings, I’ll edit this review, lower the star rating and pitch the flask!
