Fantastic service from start to finish. The products have been made to a very high standard. Absoluteley faultless. 10/10 woild recommend.

Quality：  I ordered 3,000+ sound books, and about 50% were defective (itchy/distorted sound, broken buttons, poor finishing). I provided photos, videos proof from a random 152-unit inspection. We even had a signed agreement that defective items would be refunded. The supplier admitted the sound issue was caused by their own mounting design, but refused any refund. I contacted Alibaba support within 60 days and followed their advice to first negotiate directly with the supplier. When I later escalated, Alibaba rejected the case on a technicality, ignoring my earlier documented contact. I acted in good faith and followed their instructions, yet I was punished for doing so. The result: thousands of unsellable books, no refund, no protection. Both the supplier and Alibaba failed to honor clear evidence and agreements. Buyers should be warned that even with contracts and proof, Trade Assurance may not protect you.
