It's a Scam. DO NOT BUY. Most of these positive reviews come in the same few days. Someone was simply cranking them out using different names. UPDATE: they have seen my review and tried to tell my friend (who was trying to order) that they have been in contact with me and reshipped my unit and I was in the process of changing my review (which is completely false). Thus, they have seen my review and purposely done nothing about it. At this point, it seems like a total scam. Do NOT order from this website or any others that they own (listed below). I ordered an S19 Pro (from MiningRealm.com which the same people own) as well as the E9 (from antminer-e9.shop which they also own) and was about to place an order on here (antminer-l7.com) when everything went wrong. The customer support couldn't have seemed much better. However, they claimed they were shipping the S19 Pro to me and even sent me a tracking number for it. When I searched the tracking number, it said it was being sent to Dallas, TX (I am in Ohio), so I emailed the CEO who I had been talking back and forth with for a week or so and he told me that it must be a system error and the address was correct. Then, when it was actually delivered to Dallas on 10/25 (when it was supposed to be delivered to me), I emailed again and have yet to hear anything. I've reached out to the chat bot, emailed him constantly, and still haven't heard a thing in over a week (after emailing back and forth with only a few hours maximum in between). I was ALSO told that the E9 I reserved would be sent to me on 10/25 and haven't heard any follow-up on that either despite my pestering. I don't want anyone else to make the same mistake. DO NOT buy.
