Mining Rigs


 How Technical Support work?

You will not be left in the dark. We include 90 Days Technical Support with our mining rigs.

 How does our Limited Warranty work on miners?

Our miners are covered under our Limited Warranty for 180 Days from when we ship your mining rigs to your address. Colominer will repair the mining rig at no charge, using new or refurbished replacement parts.


 How to calculate your monthly profits?

Cryptocurrency markets are highly volatile and risky for newcomers.  We encourage our customers to commit independent research to all GPU-minable cryptocurrency technologies before making any kind of purchase from our store or anywhere else.


There are a few online resources which you can use to calculate your total hashing rate based on GPU chipsets and estimate your ROI.



Unfortunately, all presales of mining rigs are final and non-refundable. We put a tremendous amount of time and efforts to secure computer components from our vendors overseas, as well as local distributors.


Colominer has no control over logistical arrangements of GPUs or other computer components and cannot expedite them.
