Bobbie Hash Matrix stands behind every miner we sell. Since we bench-test and grade each unit before it ships, returns should be rare, but here’s exactly how it works when you need one.

90-Day Return Window

You have 90 days from the delivery date to return your order, whether the unit is defective or you’ve simply changed your mind. We accept both:

  • Defective returns — the unit doesn’t match its listing, whether that’s hashrate performance, physical condition, or missing accessories. No restocking fee applies.
  • Non-defective returns — you’ve decided you no longer want the unit, want a different model, or changed your mind for any reason. A 15% restocking fee applies (see below).

To qualify for a return, the unit must be:

  • In the same condition it was received in, with no new physical damage
  • Returned with all original accessories, including the power supply unit
  • Reported to us before the 90-day window closes

Exchanges

If you’d like to exchange your unit for a different product instead of a refund, just let us know when you contact us. We’ll walk you through returning the original unit and getting the new one shipped out. If the exchange is for a higher-priced item, you’ll cover the price difference; if it’s for a lower-priced item, we’ll refund the difference to your original payment method. The 15% restocking fee does not apply to exchanges, only to refunded non-defective returns.

6-Month Warranty

Every miner also carries a separate 6-month warranty covering hardware defects and failures under normal operating conditions, including hashboard faults, fan failures, and control board issues that aren’t caused by misuse, water damage, electrical surges, or unauthorized modification. If a covered issue comes up after your 90-day return window has closed but within the 6-month warranty period, we’ll repair or replace the affected component rather than process a full return.

How to Start a Return, Exchange, or Warranty Claim

  1. Email sales@bobbiehashmatrix.com with your order number, whether you’d like a refund or exchange, and a description of the issue if the unit is defective.
  2. If possible, include photos or a short video showing the problem (hashrate readout, physical damage, error messages, etc.).
  3. We’ll respond within 1 business day with return instructions or next steps for a warranty repair or exchange.
  4. Once your return or exchange is approved, the unit must be shipped back to our warehouse address below. Please include your order number inside the package.

Return shipping address:

  1. Once we receive and inspect the returned unit, we’ll process your refund or ship your exchange.

Re-Testing on Return

Every returned unit is re-bench-tested at our warehouse before a refund or exchange is finalized. This confirms the hashrate, power draw, and hashboard condition match what was reported when you contacted us. If testing shows runtime hours, wear, or damage beyond what’s expected from normal evaluation use, we’ll reach out before finalizing the refund, which may affect the refund amount or restocking fee applied.

Restocking Fee

Non-defective returns (change of mind, ordered the wrong model, no longer needed, etc.) are subject to a 15% restocking fee, deducted from your refund. This covers the cost of re-testing, re-grading, and re-listing the unit. Defective returns and warranty claims are never subject to this fee.

Refund Timing

Refunds are issued once the returned unit has been received, re-tested, and inspected at our Portland, Oregon warehouse. Approved refunds are processed within 3 to 5 business days of inspection. Depending on your bank or payment provider, it may take a few additional days for the funds to appear.

Orders Paid in Cryptocurrency

Orders paid in crypto and refunded will be refunded at the discounted price actually paid, not the full listed price, minus any applicable restocking fee. Refunds are issued in the original payment currency where possible.

What’s Not Covered

  • Damage caused by improper installation, incompatible power input, water exposure outside of intended hydro cooling use, or unauthorized firmware modification
  • Normal cosmetic wear that doesn’t affect function
  • Units returned without the original power supply unit
  • Returns or exchanges requested after the 90-day window has closed

Return Shipping

If the return is due to our error or a defective unit, we cover return shipping. If the return or exchange is for any other reason within the 90-day window, return shipping is the buyer’s responsibility. Do not ship a return back to us before receiving approval, unapproved returns may be refused or delayed at our warehouse.

International Returns

International customers are responsible for any customs fees, duties, or paperwork associated with shipping a unit back to our Portland warehouse. We recommend contacting us before shipping a return internationally so we can advise on the correct customs documentation to avoid delays.
