I first tried this on a heavy Irish stout and was easily able to get exactly the desired amount of head foam out of a picnic tap on a short 3/8" ID beer line, without having to change the pressure on the regulator. Definitely a great device.*Pros:*- Indeed, it is easy to take apart for cleaning and reassemble. The hose barbs are on nuts that screw on to the ends, and it can also come apart at the middle using a faucet wrench (or manually, if it's not on too tight), so you don't have to un-do any hose clamps for maintenance.- Very fine control/good articulation of the flow control "nose cone"- Good-looking, and it's fun watching the turbulent beer flow through the conical part*Cons:*- PriceOverall, this is *really* nice, though it almost seems like overkill for flow control in portable draught dispensing (the purpose I got it for), especially if less expensive alternatives exist. However, if I started a brewpub business, I'd definitely want one of these behind every tap.
