This is untested (as we do not have the hardware to test it on) but should you have any issues with the disk, we would happily accept it back for a full refund.
Will be shipped using the Letter option to the UK, so if you need further protection than a card-backed envelope, please pay for 1st Class postage upon checkout. We will ship this via a Large Letter service (this means a card-backed envelope and jiffy bag) to everywhere else in the world in order for us to offer a 'low as possible' postage cost.
