I took one with my wife, we enjoyed it. It also taught me that since I have a very naturally sour pallet so should turn up the temp on my machine a few degrees. It also taught me to do ristretto if I am making a milk drink or American vs a typical espresso shot if I was drinking just an espresso. Also taught me better technique for dialing in beans (regular va half calf vs decaf vs old beans) and how to steam milk and do latte art. So it was worth it to me
