The floor sweeper was too good to be true. I returned the products through UPS drop off service and USPS online tracking service confirmed the return but Ali Express will not honor the proof and refused to refund my money. It is such a struggle to get a refund. In the end they have both- the products and my money. It is so infuriating to be scammed. Ali Express should level up and be more ethical in their business practices. It is a surprise why they can stay in business this long with the kind of service they render to trusting customers. Even their dispute team cannot resolve the problem and it is to the favor of the seller and not the buyer.
