Perfectly fine and easy to use.
Perfect. A fuse blew in my BMW over the winter due to some frozen windows. Rather that take it to a garage I did some research a figured out the fuse was the problem. It was not easy identifying the fuse and I did not want to take them all out sone at a time. Porsche c this and it allowed me to identify the fuse within 5 minutes. Money definitely well spent.

Great product
Great product. The point is very sharp. For some use cases the point maybe too big such as interior fuse box of car. You can use a safety pin as a work around. But
