After trying this magnetizer I am very satisfied with its performance. It works flawlessly on any household appliances and is perfect for small precision screws on car repairs .The magnet is very strong, so it holds the screw securely and prevents slipping. The tool is small and portable, making it easy to bring to different repair jobs. The only downside IS that it only works on small screws, so it is not ideal for larger projects. Overall, this is a great addition to any DIY automotive toolkit..
