Review: Works - Neat little device. Strong magnet that easily goes around corners. Worked great on a couple stubborn spots that my scraper was struggling with. It's a little bigger than I thought it would be, but works well. The temp on the front display is kinda all over the place though and seems to pick up room temperature after it sits in one place too long. But its clear and easy to read when it works lol
