### ⭐⭐⭐⭐⭐ Very good quality
*by K***S on 17 September 2024*

Can take boiling liquid and subsequently crash cooled without cracking. Very robust and the markings are very clear.

### ⭐⭐⭐⭐⭐ good solid flask
*by R***D on 3 October 2023*

This is very sturdy, good quality glassware and I am confident it will survive for many years of brewing, perfect for making up yeast starters.

### ⭐⭐⭐⭐⭐ Great for making yeast starter
*by J***R on 28 December 2023*

Arrived well packaged inside a bubble wrap bag and cardboard box. I'm using it with a magnetic stir plate to make yeast starters for my homebrew. Most brewers use a 2l conical flask for their starters but I decided the 1l was sufficient for the styles of beer I brew. Very happy with my purchase so far. Hopefully it will last me many years.
