Company Details

I purchased an ASIC from them, and when the rice went up, they cancelled my order, likely to resell to a higher-paying buyer. They claimed it was because the manufacturer raised the prices, but instead of offering me the option to pay the difference, they just cancelled it outright. Avoid this company if you don't want to lose your money. I later found a reliable option in PAIVA, and within a month, my investments has yielded excellent returns.

The whole purchasing experience was quick and easy. Shipping was considerably faster than I expected it would be. Everything was good. Many thanks!

Perfect 👍 thank you

Excellent customer service - credit to Stella for friendly, professional, quick and detailed responses. Fast shipping and easy customs clearance - DHL kept me updated with numerous SMS's, emails and phone calls each step of the way. The product was also well packaged with no damages during shipping. High Quality product and no hassle setting up, I was mining within minutes of unboxing.

The service was very good and fast, the miner arrive in a very short time and very well packed. Thanks

Fast shipment of miner, one glitch is , the miner stopper to work and i tried to solve this with them, but, no luck. I had to take it out from housing and luckily seems i solved it myself. Im curious about the warranty ....

Stella in customer service was the best. Answered quickly with great insight. Also very helpful with the transaction, warranty, and delivery process. I will be a repeat customer based on your prices and quick feedback.

Super fast shipping and smooth buying experience

Good communication with the seller. Fast delivery. 100% recommend!

Fast accurate shipping and I didn't have to wait on customs shipping out of China. This meant I could get the miner online faster without any hassle.

Order was easy, and quick delivery

Excellent customer service, very helpful

Excellent customer service! I mean really top notch. Shopping times are pretty quick and a seamless process. I’ve been using these guys for almost over a year now and this is the place to shop.

Great company. I’ve dealt with them many times and have always been happy with my purchases. Fast international shipping for me.

First time ordering an ASIC and everything went very well. Even though I wasn’t able to answer any calls, it’s appreciated that their staff reaches out and available to make sure customers are satisfied with every step along the way. Will definitely look to order from CMB in the future. Thanks again!

It's a great company I ben doing business with them a long time with no problems good prices on their miners

I have 2 orders pending with them for 'June Batch' For 1 of them its an Iceriver machine wich they are not honoring the coupons for discounts Iceriver are giving themselves (and they are saying to contact your reseller for further info on how they are doing that) I can tell you, they are not doing anything or at least achieving anything, either they are bad negotiators or its bad will, i dont know what to think Second order its an Bombax EZ100, wich i received the tracking label from other vendors, and the order from cryptominerbros still on 'processing' Furthermore i already received another ASIC i bought from them that was 'in stock' and took almost a month to ship, that's not IN STOCK Already contacted them for both the pending orders and they just got no answer, just a polite response saying: 'ohh hey, we are doing our best, i will arrange priority shipping' (guess that priority shipping is not shipping within the window?) I hope they wil ship my ASICS although im leaving this review (not a 1 star because at least they answer emails) Update They offered the coupon because of this review but they don't offered the KS0 Ultra Wich the manufacturer did with the coupons, they are trying to force me to buy to KS5 series for me to use the coupon, plus they are offer door to door shipping Duty paid to the US, and because of this review they abandoned the miners in customs Update July 20th I don't see way to answer them so I'll answer here It is 100% truth, and I have the evidence. You do paid sponsorships with Red panda mining, rabid mining, etc etc. and they say that it's DDP to the US, regardless of what your website says, so I don't care what you put in your page I have evidence of every single thing I said, DHL even said you didn't answer and that's why the cargo is on hold, my June batch is still in Customs
