Firsrly, you don't get to tell people to move on. You can start a discussion by all means but doesn't mean you get to say when it's finished. Be courteous. You've been here 5 days. Our members go back over 15 years. Thing is, Thewelder, that AIOs aren't designed to be as good as custom loop. They never will be but an 80% solution for a third of the cost with 100% less hassle is an attractive proposition for those people who don't have the time, money or inclination to buy into custom loops. In this forum, we pride ourselves on being a helpful community, whether your opinion differs from the OP or not. We give balanced opinion based on our experiences and let members learn and find their own way. If you can get on board with that, then by all means, contribute. But if your first impression is a lasting one, then don't expect much conversation.
