Speed is not thesame as other actuators. Others are slower and others are even slower. It makes my frame twist.Return policy is a scam.I return the item with in return policy date. The item was not picked up. I click the option to reschedule the return. When I tried to reschedule the return, it says: "The item is no longer illegible for return." The option to reschedule return is a trap, clearly a strategy no to refund of item. This seller is not honest and not trust worth. Please avoid this seller and this product.
