They send out partially tested motherboards and hope they work. Either way they get paid.
Some people send back but my past experiences with Chinese sellers is when you send it back your usually throwing more money away as tracking ends at the china border........ unless you pay the ridiculous cost of DHL. I am now fighting with them to do the right thing but they insist they tested this obviously defective board! When I received the defective motherboard they sent me a picture of a desktop motherboard being tested.
I ordered a laptop Board! Scam companies rely on consumers getting frustrated and just moving on without reimbursement.
Reason of review: Damaged or defective.
