When i tried this product, I was impressed with its effectiveness in protecting my GPS system accessories' screen. It is very easy to install and it does not leave any residue when removed... The screen remains clear and bright, and it does not affect the touch sensitivity. The protector is durable and tough, providing great defense against scratches and dings. However, it is a bit pricey compared to other brands, but still worth it for the quality. Overall, a great product for electronics!See full review
