I would most definitely buy this machine again if I were to buy another in the general price range.
Positive Product Points
For the money, ease of use, versatility and quality of output, I cannot think of a better espresso machine. The PID is pretty easy with practice - and dials in the output temperature perfectly.
Negative Product Points
Water reservoir could be larger if not direct-plumbing. It might make sense to have a hole above the reservoir in the top cover (with a plug) to allow easy filling with a funnel.
Together with the Mazzer Super Jolly Electronic I get consistently great tasting shots. The PID and dual-boilers make this a professional quality machine in an affordable and space efficient manner. The steam wand is fantastic and my girlfriend loves the hot water wand. The guard rails are a necessary upgrade and really should be included in the purchase price, even if the purchase price needs to be slightly adjusted. All in all this is a great machine capable of handling sufficient output for a sizable gathering.
Chris and his team are very responsive and equally patient in answering what must be very simple inquires.
