An Apple MacBook Pro with a shattered screen.
In this example it’s not only the screen which is cracked, but the backlight reflector is crumpled too (see arrow in the photo) so we can’t just replace the front layers. While a lot of laptop screens are in the £30-£50 region, I was amazed to find that the cheapest replacement for this one was £230, plus I had to wait a week for it to be shipped from China.

I charged £15 to fit the screen as it’s about an hour’s work, plus a bit of time spent researching the correct part at the best price
