Let's start with the bad. There are no assembly instructions. Not really a problem if you are not a total goob. The stickier point, and therefore the loss of a star, the seal on the thumper kettle is garbage and the seals / lack-of-washers for the fittings to connect the hoses to the thumper lid ain't great. Finally, the cooling water hoses are so flimsy that looking at them will crimp them and cause a lack of cooling water, or worse, an overflow.But these are all easily and cheaply fixable. When you look at the price point on this system and how well it works once you fix the seals, I still recommend buying.
