## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Solid. Perhaps a bit heavy.
  

*by M***D on Reviewed in the United States on January 14, 2024*

These seem to be quite substantial and may be a bit heavier than most. Note that there is a plastic lip on the top of the glass which could be a problem if you need to heat these much.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Thick, durable and heat resistant.
  

*by J***N on Reviewed in the United States on May 12, 2023*

Thick glass. Not a flat bottom but still allows for use of magnetic stir bars. Anti-drip ring is essential and works well. Fit easily into Insta-pots and pressure cookers. Great product, especially for the price.

### ⭐ 1.0 out of 5 stars







  
  
    Cracks after heating.
  

*by D***. on Reviewed in the United States on May 22, 2021*

I have purchased this product twice for use as a container for yeast starter, and it works fine for that purpose but both times after autoclaving the flask just shatters. The first one broke after pouring warm water into it while it was still hot, which I assumed was my fault so I just bought another. The second one broke after simply letting it air-cool after taking it out of the autoclave. Compared to my genuine borosilicate glass bakeware (pyrex) which can tolerate ice cold water right after heating, this is a joke. I really doubt this is real borosilicate glass.
