Parallel AIO - satisfaction straw poll

Good morning all.
I have an AIO which, I have to say, after initial issues is working brilliantly and doing everything I expected of it.
I'm pondering a 2nd one. Of those that already have 2, would you be prepared to indicate whether you are pleased or if there are particular issues? It's quite an expensive option and I'd like to make sure I don't go from being pretty happy with it all to 'not so much' 😉
Thanks very much

Save your money, more trouble than anything I have ever owned (and I really mean that) do not expect any real help from GE when it goes wrong as there is only one Guy at the firm who knows anything about a dual setup, and he is not in support and engaged in much more important projects.
