I had placed an order with Derwin in October, 2013. That order arrived at ISC-NY timely. However, this order did not clear customs. I telephoned the ISC-NY and was given the complete run around. I contacted Derwin and told him what happened. On Nov. 25, 2013 he sent out a replacement for the previous order. The replacement order was delivered today Dec 4, 2013. I will definitely continue to order from Derwin. No worries is what he said, and he has my complete confidence. Thank you so much Derwin.
