Interesting; I’ve replaced both of my Pari green compressors twice and they sent me a Pari Pro Neb for my last warranty replacement. It seems to be faster than the green one but maybe just because it is new. I hadn’t planned to have 2 of them but I bought a second one at the beginning of the covid lockdown as I was worried that I might be without one if mine broke down. Thankfully they have a 5 year warranty.

I will keep an eye on the cups to see if they’re working properly - I’ve never really done that. Thanks for the tip.
