"A fiver to your favourite charity if they last more then 50 miles or survive your 1st decent pothole (whichever comes first). I'm honesty surprised you can even sit on it without them bending and buckling."
So that'd be a fiver to the coffers of Diabetes UK (http://www.diabetes.org.uk/get/donate.htm) please. Currently at around 55 miles (My planned long ride was curtailed due to being knackered so it had to wait until I'd tallied up the miles commuting). No signs of imminent (Or future) failure so far and having tweaked the handlebar position, she's even more comfortable.
If you're ever in Edinburgh, you can have a go... if you dare! ;-)
