As the title suggests, this product is very effective when you have to pass the technical inspection and that it has no money to invest immediately in a new ice that costs as 80th models (in my case). The product is easy to install: I have made the cut with a pair of scissors. Here is the most. The less is that one sees not much! This approach closely distorted obstacles. In short, I knew what I was expecting I'm not at all disappointed with this purchase. In addition to the premium delivery, I was not costed much, at least less against the visit!
