I ordered 4 Speco Video Cameras from Mergui / Vision. Three weeks later they arrived, with no protective wrap; just the boxes provided by manufacturer. Three of the cameras worked, the 4th did not. When I reached seller several days later, he agreed to replace. I returned camera via DHL to Canada, yet seller refused to accept shipment for two weeks. After many emails & calls he accepted the shipment and said he would refund my money. Calls and emails later he told me he reshipped and “to get lost”. We I tracked the shipping number showed a delivery to a city / state other than mine. Bottom line is that he took back the defective camera and refused to replace it or to refund my money. Do not do business with this guy.
