+1. I use one of these in the warm/hot months. The first pour won’t be overly foamy and off tasting (like can happen with kegerator towers) using one of these. Somebody DIY-inclined could build one cheaper. I went with speed and convenience and bought one of these.
I like a good 1/2 inch to 3/4 optimally. I typically get a bit more on the first pour, but she settles down after that. I also use a fan to help even out keezer temps, otherwise the cold air loves to cling to the bottom. A typical pour starts off running down the side of a tilted glass and finishes straight down the middle. Makes me thirsty just thinking about it.
