Received an A4 4020 instead of A4 4000. Processor works, no problem!
I ordered two CPUs. However, only one arrived and the A4-4000 was not included. The seller didn't admit, he just told me to contact the local post office. So I would open dispute and decided to refund. If you buy from this seller, I think it is better to order one by one and ship one by one.
