Yes, it's just an area with a lot of truck and tractors. My screen replacements:
1. Small chip turned into crack one cold morning when I used heat onto windscreen
2. Replaced it because the heating element stopped working in few places, I think faulty screen, otherwise was fine.
3. Got a chip the size of £2 coin, impact was so loud I thought the rock went right through the screen! Came from under a bloody lorry...
Now have a chip in front of the mirror so cant see it from inside and a tiny 1mm one right in the middle of my view, it can be so annoying!
It's a daily driver and I do a fair amount of miles so I suppose these things happen
No idea on screen differences. Maybe someone else knows here?
