Query: Nice espresso but...

Machine is significantly overpriced for build quality. Weighting is incorrect, i.e. the unit is not balanced properly. When you "pump" the espresso the machine wants to tip over. The frother position and function is subpar.However, it did make the espresso well! Nice crema and surprisingly easy to use given the concerns people give you re: using a pump machine.
