I just bought the W100s from Kees.
Made contact on the Thursday, communcation was quick, clear and friendly. I received good pictures with handwritten notes confirming the pics were genuine. We agreed a deal, they were sent on the Friday and I received a copy of the postal receipt by e-mail. The cans turned up at my door first thing on the Monday morning. Exactly as described and well packed.
I'd glady deal with Kees again and would recommed everyone else does the same
