The initial shipment arrived in an undersized box and the product was physically cracked upon receipt. the carbon pattern had many defects as well as a rattle within the canard. I requested a refund, but the supplier refused and shipped a replacement product while a refund application was pending. the supplier cursed me out in private chat because of the pending refund application although he shipped parts that I informed him that I no longer wanted. the new parts were totally different pattern, demonstrating a lack of predictable supply control, and quality. the supplier is highly unprofessional and I recommend not engaging.
