Customer Reviews
Smooth purchase of accessories
I bought a PDU for my mining rig and some Accessory Cables from Bitmars. The ordering process was smooth, and the website was easy to navigate. I received an order confirmation right away. Shipping took about 6 days, which was within their estimated window. Everything was packaged securely, and the items were exactly as described on the site. I didn't need to contact customer support, which is always a good sign. The PDU integrated well with my existing setup, and the cables felt durable. I appreciated the detailed product descriptions which helped me choose the right components. Good experience overall for accessories.
Good miner, shipping was okay
I purchased an Antminer L9 16G from Bitmars a few weeks ago. The miner itself arrived in good condition and has been running as expected, which is the main thing. Setup was pretty straightforward, no major headaches there. My only real gripe was the shipping time; it took about 8 days to get to me, which felt a bit long compared to other online stores I've used for electronics. Customer service was responsive when I inquired about the tracking, so that was a plus. Overall, a solid purchase, but they could probably speed up their delivery a bit.
Great value on Antminer S21
I was looking for a good deal on a new miner and found the BITMAIN Antminer S21 XP 270T on Bitmars. They had a pretty good percentage off compared to other sites I checked. I also got free shipping, which definitely helped with the overall cost. The miner arrived without any issues and works perfectly. For a first-time buyer like me, it felt like a smart purchase and I got good value for my money.
Fast delivery, good product
Ordered an Antminer S19. It arrived quickly and was well-packaged. The miner works great. No complaints.

What's their return policy like if I get a miner and it's not what I expected?
Are these miners actually new and genuine from Bitmain? Worried about getting fakes.
Anyone know if they do any special discounts for first-time buyers? Or a coupon code for new accounts?
Thinking of getting an S21, but also looking at Whatsminer. Any opinions on Bitmars vs buying direct from Bitmain or other sites?
Hey, wondering how long it usually takes to get an Antminer delivered to like, Texas? Thinking about ordering an S21.
