wow, that sounds really bad! It hasn't happened to me.....yet. I've got two cars with them on.
Rubber went soft when car was parked in a sun for few hours, stopped wiping properly since than
If you go on Ebay, or Tesco site and you are prepared to buy Stadium for ten of any size you can pay under £1 each delivered. But I quite like the look of these. :)
Always get cheepos of flee bay delivered for around £5... work great been on over 12 months and still fine.
Why? What happened? I've had some on one car for about a year no problem
