I love my Lelit Elizabeth. Many complain about the cheap steam knob. Clive Coffee in the USA now sells a replacement hand made knob for $35 US. I installed it today, and it is lovely. I opened the case and supported the valve assembly from the other side when pushing on the knob, because it does take some persuasion to get it on there. But it is really pretty. Photo included here.
