Original post was titled "Coffee machines reliability chart", but the image says that they're in the "espresso machine category".
The biggest swiss online seller makes charts for warranty claims. Basically: how many warranty claims does each brand have? This chart only shows the most popular brands of coffee machines sold on the site, but I still find it interesting.
I only know the first three companies on that chart. I had a Gaggia Classic someone gave me and when it failed bought another one. When that failed five or so years later, I bought a Sunbeam. Imo it makes better coffee and was half the price.
Choice magazine in Australia does reliability surveys for appliance, electronic and a few other things. The one that remember was for fridges, where Smeg was the most expensive by a good margin but least reliable.
I've always been of the mindset of "pay the least amount for a product that does your desires goal well enough for your needs". It's why I've had a Mr. Coffee seni-automatic cappuccino machine for over 10 years. Not a Rancilio, but certainly good enough for what I wanted at the time. AND, it was $35 on sale at the time.
