## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Warming my kombucha nicely
  

*by L***S on Reviewed in the United States 🇺🇸 on February 18, 2018*

This is the first kombucha heater I have ever purchased. It is warming my brew and is working as promised. I wish the strap was just a tiny bit longer to better fit around my 2 gallon continuous brewer although it does (barely) make it around the jar. It was an excellent price and came with a thermometer strip. I would recommend it to a friend.

### ⭐⭐⭐⭐ 







  
  
    but used an unused narrow belt I had on hand to attach it and it works great!
  

*by D***A on Reviewed in the United States 🇺🇸 on January 18, 2018*

Worked well this brew! One of my crocks was too wide for the Velcro fastener, but used an unused narrow belt I had on hand to attach it and it works great!

### ⭐⭐⭐⭐ 







  
  
    works great
  

*by A***R on Reviewed in the United States 🇺🇸 on November 11, 2017*

works great for my kombucha brewing. helped so much for speeding up brewing time in the winter months. i keep it loosly around my jug and it keeps the temperature around 76 degrees.
