Thankfully, I didn’t trust those fake negative reviews. I was invited to a video call so that I had chance to saw their real company environment and business registration by myself. Actually, they run B2B business over 14 years and their business is also on multiple platforms like Alibaba and Made-in-China. These platforms have strict auditing systems for examples SGS and TUV will be asked to check the business’s address and authenticity to confirm if it’s a real business. Now, I become one of their client and my order of 110 units Antminer S19 pro 110T was fulfilled well. I suggest you to talk to their sales expert and check the authenticity by yourself instead of listening those fake reviews post by someone who you never know before.
