Hi,
I have one of these (2014 16 GB model) that I no longer want:

Long story short, I broke the ribbon cable that connects the R1 and R2 buttons to the system board while disassembling the device to inspect the wifi antenna. All other functions work fine. Would the devs find this useful if I were to donate it? If so please PM me with a postal address to send it.
Thanks.
