I've bought 3 sets of these from him. 1 black, 2 blue. All items arrived in mint condition and well packaged. The only criticisms i have are that he can be a bit slow to reply to messages (i think he works nights-although i dont see how that justifies him taking a few days to reply), and his postage charges are a tad high. I asked him if there could be any reduction on postage costs and he said no. He did combine the shipping when i bought 2 sets of tyres, but i had to send him a request, then wait for a few days for an invoice. I would buy from him again though, as nos cheng shins are getting harder to come by.
