## Customer Reviews

### ⭐⭐⭐⭐⭐ Works really well
*by C***Y on October 15, 2024*

It amazes me how little of this is needed to prevent boil over or krausen. In a 5-gallon batch it only takes 3-4 tiny drops. It’s also very useful in making yeast starters so that your Erlenmeyer flask doesn’t overflow.

### ⭐⭐⭐⭐⭐ LOVE IT!!!!!!!!
*by P***E on February 7, 2020*

This works wonderfully. I use a ROBOBREW 35L and while doing my last 2 brew not even an attempt to boil over. Love it.

### ⭐⭐⭐⭐ Zero boil-over
*by A***K on June 28, 2022*

This definitely worked for me during my boil
