No response after two weeks of sending an email. I have the exact same problem as the above poster(s) and would at least appreciate some confirmation that my email was received. Sent on 12/27/2015, it's a little past due for response.

After about half a year of owning this keyboard multiple keys started to double press, including the e, d, a and space keys, among others. For whatever reason I cannot find the product in my order history, but I do have the invoice in my emails saved. I've read that this is not an uncommon problem, but as it has a long warranty I'd like to take advantage of that. I probably have the original packaging in my garage somewhere, but I hope I don't need it in order to send it in. Letting me know what to do would be very much appreciated.
Thank you"
