Regarding the lack of accessories, we are actually very aggrieved. Amazon has also checked our products. Our new product accessories are all complete. (You can imagine that if we plan to send 100 sets of products, we will prepare 100 sets of pulleys, 100 sets of mounting brackets, 100 sets of end caps, 100 sets of screws......., when any set of products misses a certain accessory, then there will be accessories left in the end. In fact, all accessories are completely packed into the product packaging, so there is no possibility of missing accessories.) Then why do customers report that there are missing product accessories? In fact, the products with missing accessories are returned by buyers and resold. Since this product has many accessories, buyers may not return all the accessories when returning or exchanging goods, and Amazon staff have not confirmed whether the returned goods are complete before repackaging and selling them, so there will be missing accessories. Now, please pay attention to all customers. If you find that the accessories of the product you purchased are missing, please purchase the accessories here. Thank you for your understanding. In order to express our apology, our accessories are sold at a loss and do not make money. Thank you again for your cooperation!If you don't want to buy this product (because you have already paid and don't want to pay any more for accessories, please contact us and we will send you the missing accessories from China. Although this is not cost-effective for us, it is indeed our responsibility and we are willing to bear it). In short, we want to solve any problem for you, just contact us, thank you.
