Dear customer,
Thanks for your interest in our product.
We're arranging the shipment of S7 following order of full payment at the moment. But sorry to inform you that we don't have so many units that with announced hash rate of 4.86th/s miners. Right now, we have some miners with 4.66th/s and would like to ship them to you, for the missing part of hash rate, we'll provide you some refund. May you confirm whether it is OK for you?
Sorry for the inconvenience.

do anyone get this message ?
