So far the cup seems to be good enough however my issue is with the Sales team I ordered ADV L4 100 with black rubber cups. We agreed on a specific price and I and I received. ADV0 400 with white rubber cups that information was never disclosed tothe shippit was was a total nightmare received the cup 2 weeks. Later then Our agreed upon. Delivery date after the salesman made the cell he was way too busy. To spend time on helping me figure out where the cup is. The packaging was very minimal. I'm surprised the machine was not Destroyed and transit. It is too soon to say how quality the machine itself iso far. It seems OK.
