BITMAIN USReviews of bitmain.us.com

The order took a very long time to be delivered. My KDA KA3 miner arrived only three weeks later and in damaged packaging. But overall the product is good.

Very helpful in helping me get the most efficient Bitcoin miner for me. Very fast delivery. Good customer service. Great service.

Once ordered they keep your u up to date with every process they are going through.

This is the third miner I have ordered over the years. Runs flawless. The only replacement part being the power supply. Delivery has always been faultless and on time.

Bought some antminer parts it said shipped all of the items and once I got one of the product, they added a new tracking number for the others that will come another week later. Very misleading, if I knew they were going to pull something like that, I would have of just purchased at Amazon and get it the same week with prime.

This is the third miner that I have bought from Bitmain US. I ordered it on the Monday and it was delivered the following Saturday.

I made a purchase, which was confirmed and processes, then canceled TWICE, refunded TWICE. I called my bank, egg-brains customer service twice. I text the chat agent 3x. have the transcript them giving me multiple different reasons as to why my payment wasn't processed. The customer service people wouldn't try to fix my issue only blame my bank, me or prior customer service agents. I'm no closer to a answer 8 hrs later. THE WORST PART IS, that same card at the SAME PURCHASE did process one of the parts I ordered. (now being shipped to me) even though they canceled the other 6 items on the same order and calmed my card can't be processed? I know this sounds are vastly incompetent.

Unfortunately, I was thoroughly unsatisfied with the whole process of buying KDA Miner KA3 from Bitmain US. The delivery was extremely slow, the payment process was fraught with with problems, and customer service didn't respond to mu inquires in a timely fashion. I don't recommend anyone use this online store as they are unreliable and unhelpful when it comes to customer service.
