I have bought two of these solar cameras and they are excellent. Very easy to install and invaluable for parking and rear view. If you have an old convertible - we have a 2002 Saab 9-3 - then you know that visibility is great with the roof down and a real problem with the roof down in inclement weather. You will be grateful to me for recommending adding this camera. One caveat - the solar panel must be protected from permanent moisture, as the label warns you. This is not a problem while driving or when your car is in a garage, but leaving the solar array exposed in the snow for days or weeks is not recommended. A plastic bag over it should help if sealed tightly.
