Sorry, only saw this now but I don't follow entirely but assume you're referring to me as you quoted my post. Just to be clear (and despite the letters in my nickname), I have no affiliation or contacts with that company. I've never even heard of it until now...
Yes, I am quite familiar with Whatsminer products as I have ordered a bunch of both M10 and D1 from Pangolin.
I've ordered a bunch of miners from them already with no issues?
Please be aware the DJ Technology Co. Ltd. is supposedly another distributor. So seems interesting there is a newbie "copper memeber" who is very familiar with Whatsminer product in this thread.
Are there reputable members who have purchased from whatsminer.net?
