### ⭐⭐⭐⭐⭐ Great value

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

This is my favorite 1L rbf, now 😊

### ⭐⭐⭐ Mids
*by S***. on March 13, 2023*

Came with a few cracks in the glass, the worst being on the ground female joint which makes heating from below, as well as clamping in a stand a bit worrisome. However, I haven't had any issues with my purpose for it. Maybe consider something more reliable if planning onĥh cold shocking or applying intense heat directly. Shipped from China if I remember correctly. Didn't take too long.
