Replacing a fuse is very, very difficult and completely illogical. You have to remove the orange cover, which is very hard to remove and won't last long, then remove 4 screws to finally access the fuse. A product to avoid.

It's okay.
If you want something professional-grade, you can't just ask for that.
It seems like it would be best for people who use it occasionally.
