I have one, about 30 brews into it. I love it. I've retired my three tier system after brewing on one. I only have the 120v so it takes awhile to heat up to mash temp and from there to boil. That's the only drawback for me. They have the higher power one available now even though that still wouldn't be an option for me. My brew days are about 4 1/2 hours typically, including clean up. I'll start heating the mash water and mill my grains, measure out hops and brewing salts while it's heating. Pretty painless. Set your timers and check on it when it's time but I love the convenience of brewing indoors especially when it's damn cold outside (or too damn hot!). Makes some outstanding brew. Overall I give it an A. I would buy it again. Cheers!
