No affiliation with the company etc. I got one of the hydras about 10 days ago and tried it for the first time this past Saturday. Lived up to its rep completely. 6.5 Gallons from boil to 68 degrees using 66 degree water in less than ten minutes. The thing is very well built. Didnt fit in my small 7.5 kettle (with a temp probe buil in it) but I never do my boils in that kettle anyway (I was just trying it in there to boil it out once before use and clean it etc). I seriously considered a pump and plate chiller etc but am completely happy to no have the added cleaning etc. If you are considering an immersion chiller I cannot think of someone making a better one than this thing period.
