Te pongo la descripción:
"How long does it take to clear your screen in cold, damp or wintry weather? Once cleared, it can take up to ten minutes for the heater to keep it clear.
How many of us have driven looking through a porthole shaped patch?
Our heated screen will clear in approximately three minutes and will keep it clear and safe.
No more expensive than replacing a non heated OE screen.
These screens are produced as
an exact fitment to your S1 Elise.
Same install as a standard screen and supplied with a timed relay switch so you cannot forget to switch it off.
We can arrange a fitting service throughout most of the UK.
It can also be installed by any proper windscreen company. "
Yo por el precio y lo que te he puesto en negrita apuesto por que sea un cristal de sustitución con un sistema antivaho, no sé recalcan mucho el "no vas a tener problemas para instalarlo y que ajuste perfecto en tu elise"
Tiene buena pinta
