I've got a few of his moulds. The product is very nice but I'll not deal with him again. In addition to the poor customer service and communications hinted at in other posts, the way he used to run his group buys (disorganized, done with no respect to order so that some buys were done in weeks while others stretched out for years, absolutely no status updates) struck me as displaying a remarkable contempt for the paying customer. I've received very nice moulds from other producers, too, without the attitude.
I believe he quit his job a full 3 years ago to focus on mould making full time, so there is no excuse in my mind.
