Thus far I'm not very impressed. I drive a 2011 Lexus 460 and still have a big problem reaching all of the glass from the back seat. Plus it still doesn't clean as good as it should. I'm not sure there is really anything that will clean the inside rear window with minimal work.

Really strong, sturdy handle. I always somehow get plastic dressing on the bottom of the windshield and could never get my hand far enough down to get it but this solved the problem.

I bought this tool to make cleaning the inside of rear windshields a little easier. That said, I now use it on the front windscreen as well, just because it works so well. Makes cleaning corners and odd angles much easier.

Bought this from w**mart, it's convenient but the build quality is 3.5/5. Consider buying only if there are corners/edges that you really cannot reach by hand.
