I used sugru to repair my MacBook Pro - the feet had come off the bottom meaning it would seriously overheat when left on a flat surface. I split a packet into four?pieces, rolled them into balls then placed them on the corners, finally pressing them down to form circles. I then softened the edges and left the MBP upside down to dry for 24 hours. I now have a MacBook Pro that sits far enough off my desk as to not overheat and sugru made that possible! Andy, UK.
