Lelit Elizabeth and Niche Zero. The former approaching its 3rd birthday and working flawlessly. I never descaled. It still sounds and behaves like when it was brand new. The later two years older, no issues, hasn’t missed a heartbeat and still going strong.
Previously, had two La Pavoni and they were good too. Had a Pro-700 before that and the control box had to be replaced one year in as there was a malfunction with the level sensor.
Prior to that I had a Rocket Cellini Evo. It’s crime was to come out of the factory not lubricated enough. I didn’t have a clue back them, so it only lasted 3 months in my hands and swiftly returned back to BB.
Prior to that had a Gaggia Classic which ran on the finest Thames Valley tap water at 300ppm if not more, for 3 years. Bought in 2011 new. Never had a problem. The machine is still going strong (and so is the Mignon Grinder) in its no longer new home in Sydney and potentially still being fed some amazing tap water from the Southern Hemisphere.
Amongst some of the coffee roasters I owned, I bought a lemon Behmor which had a miss lighted shaft. It was excruciating to see and hear it turning. Swiftly returned as faulty back to where it came from.
