Thanks for the info! No refund needed and I will sign up to give it a try and see. I have a particular use case in mind for the relays and because I want to make sure it's sustainable, I need to be careful with my set up and budget from the beginning.

I don't loose nothing giving it a try, best case scenario it does work for me, worst I would have support at least for a bit the project! which I think it's an awesome and needed one.
