“Installed as a "hack" on my Alex Duetto 3 with GB-5/FB-80 wand, it works fantastic as I was not too exited spending $$$ on a knife/vortex tips. It's so powerful, milk is frothed in 5 to 10 seconds instead of 1++ minutes, I feel like I transformed my Duetto in a LaMarzocco! :D Now I can finally practice my latte art ;)”
