Good good seller, I bought one for myself and one for my wife a few months ago. Very satisfied as he has reasonable price and he lets u try a whole range and bunch of stocks. As for warranty, no worries, if u r unsatisfied about something reasonable on the pair u purchased from him, he will try his best to make sure u get what you wanted in mind. We met up again last friday at ikano, coz my buddy and his wife also wanted to buy a pair each for themselves. They managed to choose the ones they want even though it was dragging up to late night, there were no complains. I think there are more people from my circle who will purchase from him very soon. So all in all, thumbs up. Cheers.
