I must say I'm very happy with my machine. It pulls perfect shots almost every single time, and like all machines, you need to get the grind size, volume, and tamp right. This machine is also a true beauty to look at, and never fails to attract comments from guests. The only difficulty I had initially was in fastening the portafilter onto the machine once it's tamped with espresso grounds. The trick is to hold the machine on the table against your body, with one hand holding onto the metal rail at the top of the machine, and then using your other hand to yank the portafilter tight. You'll get used to it after a while. For the price and the quality, not to mention the portafilter is superb heavy duty at 18 inches in diameter, I have no regrets buying this machine, and highly recommend it!
