tip December 6, 2017
Reviewer: C from N/A  
not easy to see in the picture is that the tip is sealed the cheapest way possibly. the simple flat crimp and weld (without grinding/polishing) are not only ugly, but enlarge the diameter of the well tip. if you only intend to use it with a stopper (as it comes with) it doesn't impact functionality, but if you plan on slipping it through a keg port, it will not fit through

Stopper Thermowell October 11, 2017
Reviewer: Jeremy Coghill from Toronto, ON Canada  
While this thermowell does live up to what it is billed as and will fit the temperature probe from an STC1000, it is a bit of a stretch to say that it is a #6.5 stopper.  The only way this fits a #6.5 opening reliably is if you have jammed a large enough airlock into the blowoff hole.  Otherwise it will likely fall through the opening.  A larger stopper would be quite nice.  I like the item, but am rating as average as it really should be slightly larger or listed as max #6 stopper.

My fermentation chamber loves it February 22, 2017
Reviewer: Jonathan Jacques from L'Ange-Gardien, QC Canada  
Since I got this Stopper Thermowell, my temperature controller in able to keep my beer temperature within .3cel of my target temp (Versus over 1celcius when I used to tape the probe to the side of the carboy).

Put the airlock prior to stick it in the carboy!! January 10, 2015
Reviewer: Jean Ratté from Québec  
The first time i used it it felt into the carboy because the silicone stopper became slippery due to the starsan on it! If you put the airlock into the stopper prior to stick in in the cartboy you'll be ok!
