Nice unit. Not for my windows.
Despite having an adjustable magnetic intensity, I could not get this to work on my 1993 double pane with aluminum between the glass channel windows. It just kept falling out. The adjustable feature pushes magnets inside closer together so, I assume, they contact each other. The adjustable screw does not stay at any of the settings, it flips back to #1. I found it hard to hold the outside scrubby part, the inside scrubby  and adjust the gear at the same time  to try to get this to all stick together, which it never did. My windows must be too thick. In the description, it does state what thickness this works with, but I did not know how thick my windows were., They are obviously beyond the stated tolerance.<br />I think this would work quite well on the right windows. It is one of the less expensive magnetic cleaners and is a nice size to manipulate. Plus it came with all the extra parts. Try to determine your glass thickness ahead of time.<br />The extra pads, extra squeegee strips and locking gadgets for the pads is a great feature and one of the reasons that I ordered this cleaner. I was disappointed that it wouldn't work on my windows. I am not giving it 5 stars, because it doesn't work with all windows.
