Yes I will continue to patronize him as long as he remains friendly and somewhat reasonable on prices. For example he sells a 5 pack of quad coils for the TFV4 for $30 out the door. Seems so reasonable to me I have not even bothered to compare prices on line.
Don't get me wrong he did not WANT to take the M80 back - but he did want me to have a working mod. He went so far as taking it apart and seeing if he can fix it before replacing it, but I expect nothing less. He did question my charging habits, but over all was a pleasure to deal with.
I had a simular experience at My local shop, with a temp control device i recently bought, just couldn't get it to work, took it in told them what was happening, they asked a bunch of questions and started experimenting with it with My build, and it did what i told then it was doing, put my build on his device, same model as mine and it worked fine, His build on my device acted like mine did. And although he said my build was "good" he asked if he can do a rebuild on it and give me some pointers, which he did, they replaced My device. All through this they were friendly.
