Looks very good.

Perfect!

It cleans well, its problem is at the corner of the window but still good.

cool thing, but the windows won't close after repair. It perfectly cleans windows simply stained by street dust.

Don't know about its future at the moment, after using it on several balcony windows - just great and does the job perfectly.
