I ordered an AquaXtreme MP-05 LE Pro waterblock from them. It arrived very quickly (in two days) with the cheapest shipping, USPS. The service is absolutely great. When I discovered, upon arrival, that the midplate was a little damaged, I contacted CoolTechnica. They sent me a new Delrin midplate replacement (with no additional charges, FREE!) that was better than the one I originally ordered . VERY IMPRESSED! I Highly Recommend them!
