First of all, I'm sorry to bring you a bad shopping experience. I thought it would be a business for us to open our future cooperation, so I offered you the best price in your heart, provided you with the best high-pressure diesel pump, took videos and pictures for you, and provided you with a quality guarantee. Finally, I didn't get your reply, but got the worst review.My goods have quality, I told you before you buy, you can contact me, you can return the goods, or negotiate with me, I will correct for my own bad, but need you to tell me, friend, finally, wish you have a good day
