This machine is so easy to use and makes a great espresso. Much more cost effective and environmentally friendly that pods. Plus no chemicals or stale coffee concerns that some pods present. I love this machine and wouldn’t be without it. 
I gave 4 stars because the app to make adjustments to espresso shot amounts is a bit janky plus the waste tray sometimes says empty when it is not full. The lack of LED screen also takes some getting used to. I would certainly buy this machine though if you are in the market. Automatic grinder is a game changer in the morning! 
You can descale this with 50/50 water/white vinegar so don’t go out and buy expensive chemical cleaners, vinegar works GREAT. 
Enjoy!
