## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value
*by C***M on February 5, 2024*

Good quality, no issues with its use. As good as other higher priced flasks out there.

### ⭐⭐⭐⭐⭐ Nice piece of glass!
*by J***N on May 1, 2024*

This is my favorite 1L rbf, now 😊

### ⭐⭐⭐⭐⭐ good quality glass and a well-finished joint
*by A***R on June 1, 2026*

This flask arrived in good condition and feels well made right out of the box. The glass has a nice clarity to it, so it’s easy to see inside, and the thickness gives it a reassuring feel when handling it. The ground joint is clean and smooth, which makes connecting it to other pieces straightforward. It seats properly without needing extra force and feels secure once in place. That makes setup feel more predictable without needing to fuss with alignment. The round bottom is evenly shaped and balanced, so it sits well in a clamp or holder without shifting around. The overall shape looks uniform, and there aren’t any noticeable defects or uneven areas in the glass itself.
