Query: Great crema but poor reliability

Sadly I am returning this machine...for the second time. The first unit I got leaked water onto the counter. I figured it may have been damaged in transport so I sent it back. Amazon sent me another one as soon as I notified them of the return and I had it before I had even sent the bad one back! About 8 weeks later the second machine had the same leak! Too bad since the coffee was really good! A couple of other items. It's a good idea to run a plain water pass through the head before brewing to bring the whole machine up to temp. Coffee temp out of the head measured about 180F which is a little cool for proper espresso. I would have also liked the two cup espresso receptacle be larger.Big kudos to Amazon for great customer service with both the exchange and return!!
