I have had this piece of equipment for a little over a year now. As someone who was new to pasteurizing at home, this model was easy to "figure out" and is simple to use. It can sometimes be hard to get the sealing piece attached so that the rubber ball is in the right position to completely lock the canister. However, with practice, it becomes easier to do. It is efficient and overall, very simple to use. I have recommended it to friends who are looking to start pasteurizing at home. We have noticed no change in the flavor of the milk.
