BITMAIN USReviews of bitmain.us.com

Took a little longer than expected, though was very quick after I queried the delay. Hardware works fine. I'm having trouble installing OS, but that's only to be expected.

I ordered three things. A mining case, fans and a controlboard. The case was on time because it wasn't dropped off at smart post. Stupid idea, btw. The controlboard, which is what I need to complete a build is STILL not here after 6 days of nothing. I am in the same city from where it was shipped. I should have just payed the extra money for Amazon to give me the controlboard. I will never use BitmainUS again. Shipping sucks here.

Antminer arrived with a piece of one of the case legs snapped off. Not a huge deal but not something you really want to see when first getting it out of the box. Everything seems ok after the first week, no issues so far.

I ordred S19 pro and paid for it, so instead of getting the item shipped, I get an e-mail the next day stating that my order was cancelled which I never cancelled;

Glad with the specs for the price was well packaged and secure for delivery. Would definitely recommend to people who are interested in mining machines.

I have been a longtime Bitmain US customer. I recently had a return of an item. The reason for the return was the item was not compatible with my miner as a controller. This risk was not listed in the item description. I was able to return the item but I was not reimbursed for return shipping, which was half the cost. Bitmain US would not refund all my money.

Have bought from the company numerous times. They offer deals from time to time but you have to be careful and check elsewhere. They were much better with deals that couldn't be matched in the past. Not so much any more. There is far more competition in there area online now. Where they particularly stumble is with their customer service. Where I did have a problem either with a product, shipment, return or whatever they were always quick to make you do the heavy lifting in getting a problem rectified. You needed to push then too often to get your problem resolved.

Last summer got my Antminer L7, but this is the second time, this has happened...."order now and get in 2 days" or whatever, only to have to wait weeks or more and get the midnight "sorry but we don't have it" email. This happened to me for a control board for L7 and a pre-order for Antminer KS3.
