    I have this and love it. Getting it set up (wired and settings) is a bit challenging but once it’s running it’s awesome. Changing temperature for say stepping up during ferment isn’t super simple but once you understand how it works it’s not a problem.

    I built a simple paint can heater to take advantage of the dual stage function so I can ferment in winter without messing with my setup.

    I also built a junction box with a light switch (master power) and outlet (one hot and one cold) like one of the pictures show in the amazon listing. Makes it easy to mount and be able to turn off an on.
