I am wondering if anyone has this installed and can give me a run down on how they find It?
We got it when we bought this house new 6 years and they have had to come back and redo it twice now, which is becoming very frustrating. Basically after about 6 months it stops being particularly effective.
If something has a "lifetime of the glass" warranty, do we continue to demand they reapply it every couple of years? Last time they offered us a refund, but ultimately I'd rather make them come back and fix their system and I wanted to know if I am within my rights to do this?
