Auto window closers

Hi,

What is mean by auto window closers and how it function in car?

It is a relay which automatically closes your windows (you need to have power windows) after some time(say 1 min) when the car is locked and windows are left open.This adds to the security feature of the car along with your anti-theft/remote lock system. The negative side is more battery consumption (not sure how much is that).

I have a Aveo U-VA LT car which have anti-theft/remote lock system fictory fitted. I want to install the auto window closers from RD (Rajatdeep Overseas Private Limited). Please suggest wheather it is good or not.
