Product Works -My Window Doesnt

My criticism isnt of the product -it works just fine, or did until I stopped using it. The problem is with the assumption that an auto window is a stable platform. My car window moves considerably with this clamp on it, enough to negate positive effects. Im better off just leaning on the windowsill. Check the stability of your windows before buying this one.
