1.Delivery: It would be better if there is advance notice before start packing to cover what really need to complete packing.
2.Design: Follow to the design specification.
3.Quality: I found detective products about 50%. I'm not sure how you check the quality of all products. So, I ask for making a claim which you deny all responsibility. Although, I'm ready to negotiate for compensation amount that can be possible for you. You inform that the goods meet current production standards and product prices. So, I can't expect high product qualilty at this price. We recommend that you should inform in advance about product quality which it will be like at this price. In case of I cannot accept the quality, the new price can be negotiated again. I think it would be fair for both of us. However, we're all looking for good partners, so I hope you will show some responsibility and professionalism.
4.Service: Feedback after sales is slow. I need to follow up often. We expect more professionalism.
