Parts I ordered functioned well and mostly as expected. It could be noted in descriptions that some parts will work on machines other than the one listed like the group head gaskets I ordered for my Rancilio were listed as being for a Cafelat but the dimensions were correct (within 1mm) for the Rancilio. I ordered this because there was not a silicone gasket listed for the Rancilio. I also ordered a brew switch for this same machine that was not listed as being for the Rancilio nor that it could be a brew switch. In other words, parts need to be better cross-referenced and identified with key words.
