This product is highly recommended. We had the Gastroback for frothing milk - but no comparison! Cleaning is per machine - through the stainless steel there are no rough surfaces or so - it can be super easy to clean. The milk froth is fine - until cold, then hot foam: this is a heavenly pleasure. And with any milk, no matter whether 1.5% or 3.5%. The volume is very limited - really well done. We are very satisfied and look forward every day - whether on Sundays or weekdays - our great latte or Capuchino. The only problem: You are pampered and want nowhere else to drink coffee!
