I just got a reply from them, and they sent the email template they use in cases where a faulty keyboard is sent out and needs RMA within the first 30 days:
"I'm sorry that you are having troubles with your new keyboard. We can do one of two things:
1. We email a prepaid return label, and you pack up and ship the defective keyboard in new condition with the provided label. Once we receive the returned defective keyboard, and have inspected it to ensure it is in new condition; we will then ship out a fully-functioning keyboard. If for some reason the returned keyboard is missing any items, or is not new for any reason, your original purchase will be treated as a standard return and restocking fees will apply.
2. If you would like faster service, we can email a PayPal invoice for the cost of another keyboard, and then once paid we will ship a checked replacement out to you with a printed shipping label for use shipping the other keyboard to us. Once we receive the defective keyboard, it will be inspected and if not in new condition, or missing any parts, the refund of the invoice will be assessed additional fees.
Please let us know which appeals most to you.
However, we need to be alerted within a certain number of days of receipt. If you wait until day 29 to say something was wrong from the beginning, a restock fee will be applied to the return.
BUT - if you return the keyboard to purchase another, no fees are deducted from the refund. If you return a keyboard for a refund, but no replacement, that's when fees are applied."
This seems pretty reasonable and accommodating to me, so I will expect this from them for customers henceforth.
