  • Great product, does what it says
Size: 3"x20"
I am using this for making kefir. I wrap it around my jar. Although you can’t control the temperature, there’s no need to buy the pricier ones with the dial. Simply wrap it loosely around the jar and the temperature will adjust accordingly. The kefir manages to stay within 70-80f range for me depending on how loosely or tightly I wrap it. ... show more

  • This belt works as promised
Size: 3"x20"
I bought it for my sourdough starter and my husband's Keifur. It really works. My sourdough starter activates in lesss than 4 hours and my husband's getting consistent results for his Keifer.

  • Works like a charm

I make kombucha and this, Matt keeps it at the right temperature and formed really nice thick Scobies. Works like a charm.

  • Works well

But I wish it had temp control.

  • Great for sourdough baking
Size: 3"x20"
I've been using this to keep the temp perfect for both my sourdough starter and bread dough when I'm proofing. My kitchen gets incredibly cold and this has been the best solution. I don't wrap it tight around the starter because it'll get too hot. I just have it gently curled around.

  • Use it for sourdough starter
Size: 3"x20"
Works great either loosely around your sourdough starter jar or wrapped tight with the rubber band included above the level of your starter. Maintains constant low heat.

  • Uneven heat
Size: 3"x20"
It seems to work ok but seems like the heat is uneven or like it’s barely warm. I use it for kombucha and wish it was slightly warmer for the cold winter months for faster brewing. Also my rubber bands that came with it broke quickly from the heat/being stretched.

  • Perfect size
