Not sure why they need a product review. This is a backup. It's been made the same way for over half a century and I doubt you can tell the difference between what was made in the 1960's and what's made today, other than they're not the cute ones anymore use small boxes of five fuses, which is sad. They say they don't make them the way they used to be. Well, they're made exactly the same as before, probably on the same machines. This is of course the best brand for this type of fuse and it will certainly be the right size. Some of the competitors they sell today are actually a bit small.
