Dovina

BUYER BEWARE IF PURCHASING USED EQUIPMENT from Shenzhen Dovina Electronic Technology Company Ltd. Know that it may arrive damaged FROM THE SUPPLIER and or may under perform. I purchased 2 miners and 1 was perfect and 1 came with boards that would crash. Just know, USED miners do NOT have any type of warranty and is NOT protected by the Alibaba Trade Assurance platform. THIS SELLER will do NOTHING for you but keep your money. I'm out $1000 US. I've spent 23 days in discussions proving my case to have the rep simply give the incorrect information over and over again until Trade Assurance closed the case. Now, this is VERY IMPORTANT if you are going to purchase from them. PRIOR TO PAYING, request the ID of the unit you would be purchasing along with a video showing the machine working consistently for a MINIMUM OF 1 DAY. Don't be fooled with a video of multiple units being tested at the same time then moving over the miner ID's. That doesn't even prove that the miner they're showing you is even plugged into the switch and or does not even tell you which computer tab applies to your specific miner. Insist that the factory test be performed ONLY on the one miner being purchased. Video should show a minimum of 1 day of hashing capabilities to ensure stability, video to include the date and time of test, then the video should move from the computer screen to follow the plugged in Ethernet cable from the PC to miner for capture the machine ID, and finally, request the contract and read it carefully, especially the conditions section at the bottom. If they did what they should have done in the first place, I could have sought damages from the shipper. In closing, Alibaba Trade Assurance reps were all professional and even wished they could do more for me. Alibaba Trade Assurance should re-revaluate this seller as a Trade Assured business as they're giving Alibaba a bad name. All this pain would be worth it if this review can stop one other person from making the same mistake I did.
