I this up from nthomebrew.com retail, this thing is crazy awesome. I hooked it up to my cheapie 1/2" harbor freight drill. I cannot believe how great this works for mixing and aerating. I mixed and aerated four carboys of mead in maybe half an hour with this device. I used to pick the carboy up and shake it, but that is risky with glass carboys. This aerator/degasser makes a cyclone in the carboy and sucks a TON of air into the must. I wish I had gotten this sooner.
I had to grind down the screw a bit, since it was a bit too wide to fit into some of my carboys, even though they were the same size and purchased at the same time, which was weird. It looks something like this. For some reason I can't find it on nthomebrew.com's site though I picked it up int the retail store ... http://www.winemakersdepot.com/Mixer...sser-P491.aspx
