Review on 🧲 Magnetic Window Cleaner for High-Rise, Double Glazed Windows 0.5"-1" Thick (15-24mm) - Glass Wiper and Cleaning Tool - Coffee Color by Eric Carr

So that didn't work for us at all. Firstly, beware of your fingers, when you put the two pieces together they have a ridiculously strong grip on each other, and on several occasions it got to my fingertips. There are small clips on the bottom which I think could easily scratch the window and the mop piece drags along sluggishly and just smudges the water. And finally, it didn't work at all on double-glazed windows. I may have missed a warning or something, but I honestly haven't seen anything about magnets not reliably penetrating glass. He literally took a hit before falling.
