## Customer Reviews

### ⭐⭐⭐⭐⭐ Took my fermentation temperature control to a while 'nother level.
*by W***E on March 23, 2021*

Not much to say other than it works great. The bung was a little too small for my widemouth carboy so I had to improvise but other than that I am pleased. Took my fermentation temperature control to a while 'nother level.

### ⭐⭐⭐⭐⭐ Worked great
*by D***J on May 20, 2024*

Worked great for my temperature probe when making wine

### ⭐⭐⭐⭐ works well
*by B***S on July 22, 2024*

EDIT: I stand corrected, it seals better than the larger plugs I got-------------------------------------------------------------------Definitely not a #6.5, barely a #6 when measured, not I need to spend twice the money to get the other half of this product in the form of a properly sized cork.Get another one, unless a #5.5 will plug your vessel.
