I had the Silvia for over ten years and never had any problems. Up graded to the Silvia Pro X because of the reliability of the brand.The Pro X is quite a bit easier to dial in with the available settings. Started to pull good espressos within a few tries. I also upgraded the grinder to a single dose Eureka Oro. I am just getting familiar with the process.
Coffee Addict has been great to deal with. Sam gave me good advice on the selection of the machines. Very quick service, I placed my order on Friday, received the shipment on Monday.
