I love my SSBrewTech Chronical 7Gal Fermenter. I had a chest freezer, and had back trouble from bending over to get the carboys out of the freezer, didn't like taping a sensor to the outside to keep temps( Johnson controller). I don't think a freezer is made to cycle on and off that much. I finally said F-- it!
Now I just fill it up and add a frozen bottle daily or heater to the water, set the temp and walk away. I can take samples any time, no more siphon hoses, drain the trub, and best of all, I don't have to bend over the at the waist and pick up that weight from the freezer (bad back of mine) or try to clean carboys with a brush.
I couldn't afford 2 grand for a conical that does all that with a built in heating and cooling features so----
What's not to like about the SSBrew Chronical with temp control
