Good Not Great
This scraper is plastic made and is fragile of course. The cover ends up falling off in no time then you will cut yourself badly. Next a few of these are warped or defect so that the blade don't fully contact the glass. The tool is just okay as I only use it when the glass material don't scratch. Most new window glass made today scratches so this tool will damage some glass. Butt older glass is made better and won't scratch with this tool. I work in construction cleaning for 15 years so I know the deal.
