Unfortunately I took a bit of a fall today, involving my ski hitting myself in the goggles, luckily nothing bad. Although the sensor mirror has gotten a scratch, as shown. Which when looking through the lens appears to be more of a blue streak(I guess it's just scratched the coating off). It's kind of annoying at times but when you're skiing I didn't really notice it, you might though.
Because of this I've decided to price them at £70, a good deal even with just the frame and ignitor(which is still 8/10, with no scratches/marks visible when looking through it).
Here's a pic of the sensor mirror scratch:
