I bought it from Wiggle.UK. After reading their return/exchange policies I'm hopeful that I won't have to pay anything if the exchange goes well.
On a side note, I don't think that I'll be able to get any pictures out of my camera because I lack the proper micro-usb cable and my improvised SD card reader is acting up badly.
I do however have a nice selection of accurate measurement tools handy, so I'm just trying to figure out how to go about getting some good measurements to quantify all of this. (my planned evening ride has been rained out, so I've got a disturbing amount of free time on my hands atm)
