This is not about Neal or any commercial seller in particular, but I would like to point out the situation from the customer's point of view:
IMHO, it's a serious concern for customers when asked to return their broken item to China, certainly assuming the customer has given undeniable proof of a defect (video/pictures etc.) before. While sending from China to anywhere in the world is ridiculously cheap for traders, it's far more expensive for customers vice versa. Moreover, it is subsequently not reasonable to send back an item worth a couple of dollars when traceable shipping and insurance would be in disproportion to the item's value. Then there's a high risk that one's parcel will be detained by Chinese customs due to declaration issues and therefore very likely to be charged for custom fees / import taxes even if it's a broken (i.e. worthless) item someone sends back for repair. Usually, in such cases the sender will be held responsible to pay these additional charges.
Bottom line: Apart from rare, valuable items worth many hundred dollars it just won't make any sense to send something back for repair/inspection unless the seller accepts to pay for shipping, insurance and custom fees/import taxes.
Aftersale service might be underestimated sometimes but word of mouth means a lot in communities and happy customers will certainly come back and buy again while annoyed customers will probably refrain from buying again.
