I love it. I have never had any problems with it that weren't easy to fix. It didn't take long to get really comfortable using it for consistantly good espresso. I have only one "Upgrade" issue, the boiler fill solenoid. Rocket (As ECM had also done) uses a small boiler fill solenoid despite there being plenty of space for a proper "Lucifer" sized solenoid. In my older Giotto, the valve closed off with calcium twice before I finally replaced it with a larger valve. With the larger valve, it threatens to block off right at the boiler inlet fitting but is easy to descale with come citric acid in through the boiler-fill-probe hole instead of pulling off valves and pipes. I descale my newer Rocket Giotto more often, and am using it with much softer city water, so it hasn't ever seized closed, yet. But I do wish Rocket was just using the larger 2-way to begin with. Some day I will change it to a larger one and can be less concerned with descaling. Rocket has made great improvements, no more "Pencil Eraser" feet. Serious "Sirai" P-stat. Nice form-fitting boiler insulation for energy efficiency (Mine is older than this improvement and doesn't have it, but I've considered buying some to add). Both of my Giottos were used before I got them and I suppose I have been very lucky that neither have ever had any serious problems (Yet). I am one of many Giotto people who am very pleased with the machines.
