It cannot be Scam
Reason:
(1) I have received the product.
(2) When you buy the product the receipt is given to you.
(3) I have contacted many peoples before its purchase that is it work perfect.
(4) The Zcash mining equihasher speed is not to big that i say it is perfect scam
A1 speed is 3200 & A2 speed is 1500 Only
those are gpu mate, there are no asic for equihash if they are scam, still you have not posted any proof that you received the product, only a video is a real proof, that show the hashrate and the earning, also what is the wattage? if they hash at lower rate than gpu why bother with this thing?
