Just what I needed! After our cold winter, some of the vinyl decals on my car's glass began to peel off. I had to take them off but there was still a lot of sticker left that made my nails impossible to use. Enter this device. It doesn't scratch my window at all. Several Desolve it and Cleanup apps and I uninstalled them all. It took about 15 minutes for each zone. You'll have to scrape a little, but it goes right under the sticker, which is way better than my old scratching method.
