I understand this product is a fake but there are 2 major safety issues with the product. They could at least check the product before it leaves the factory for quality and safety. 1) Product wiring is of very poor quality. When I switched on device my home circuit cut off electrical current to power because of bad product circuit. I investigated and found product wiring has bad soldering and wire is loose which is causing product to not work and tripping circuit breaker. 2) Forward and reverse on motor unit has been installed incorrectly from factory. This is very poor quality. Both problem shows product has not been tested for operation before sending to me. Very bad. I could of had a really bad electrical shock from product. I would be happy if seller could have resolved this outside of dispute but seller is not serious about helping and takes a very long time to reply to my messages. Avoid seller!!
