Tomthumb,
You said I have been here for a while, well haven't you? Both 18650, and SFK had there account removed when the vendor section was removed along with various other alibaba sellers account so how exactly are you expecting any response form either company. No company is going to want to engage in a place where they have been removed I have spoke to both Chris from 18650 and Tommy from SFK they both said (paraphrasing) Will Prowse is a good guy but the forums basically are run by third party sellers.
I remember reading those threads and I can tell you they both were accusing docan and a number of other alibaba companies of the same thing: selling grade B cells as A. Back then there wasn't the QR codes with a B so it was harder to tell, but test report existed then to but trying to distinguish between the 2 grades was very difficult. Basically the vendor forum was a big mess so its understandable why its gone.
As for the thread you point to its ramblings you have SFK haters vs SKF supporters (and you can add me to this because I have rept 280s from them, but I try to be unbiased, emphasis on the TRY). There is nothing everyone isn't already aware of and has made there opinion of.
18650, SFK, Ezealco and Now Battery Hookup all sell grade A cells with test reports, you can not go wrong from any vendor and there prices are within a few dollars of each other. Depending on the amount of cells you need you can select the vendor that suits you best. No one is buying 4 cells form SFK as there prices are too high, but clearly if you need a lot of cells they have the best price/cell. For me Ezealco would be the best if you need 16 cells as I can drive to houston and pick up them (even thought I have to pay sales tax). I think you and timselectric are trying to create unneeded BS drama among these vendors when you should be focusing on the fight between vendors that have test reports and the ones without.
