Awesome customer service. Installed 2kw heater, worked very well as expected but pump failed quickly. Contacted Vevor customer service, they raised a customer service ticket quickly, sent out a replacement pump free of charge and kept me informed. Great product and great customer service. Sometimes things fail and it’s comforting to know that when it happens there is good customer service to back up the product. Very happy with my Vevor diesel heater and customer service.
