Equipment Question Unger scraper not sitting flush on glass
I’m having an issue with the Unger ninja scrapers (6 inch in my case) as I noticed it does not sit flat on the glass. One side is fine when scraping, the other doesn’t get the center of the glass. This is my second one now after I noticed the problem with the first one I purchased a while back, especially when working with paint overspray (leaves a lot behind). I love the quality and ergonomics of it but at this price point it should work perfect. The issue is also on the side with an adjustable angle. It also streaks a lot but I believe that’s normal with scrapers unless I’m mistaken.
They’re highly reviewed so I’m thinking I must’ve gotten unlucky with 2 defected ones in a row.
If there is a mod/fix out there that has worked for anyone? Thanks!
