  1. It's the orange cap. 5 Star Review

    We've probably all owned one of these at some point in our homebrewing career and know all about them. They do their thing but can pop off if you have a vigorous fermentation that attempts to send krausen spewing out the top. This one, however, has a steel thermowell firmly attached to it so that's cool! Works as it should. Insider tip: I trim the other outlet on top ever so slightly so it opens wider and doesn't restrict outflow.

    Don't know what more to expect. Thermowell works as expected. Customer service at CoolZone is awesome and I look forward to doing more business with them.

  4. Does not fit 6.5 gal carboy (too big) 4 Star Review

    Product works great with Auber controller, but the description led me to believe it was the correct size for my carboys. I had to use a zip tie to cinch it down tight. I will need to order the small cap I guess.
