They are the right fuse and arrived on time, but why in such a gigantic box?
The box is big enough to hold at least 1500 of these fuses.

Works well
Works as advertised. Nicely made. Not much you can say about a fuse. Has protected my equipment several times.

Great find - Fuse not stocked locally
Bought these to replace a blown fuse in my ancient multimeter. It was impossible to find locally. The fit was good and the device is in good working order.

OK
They're still good fuses that work as they should, but I can tell quality is slipping. The box is substantially thinner than an older ones that I have and the edges of the metal lid are sharp. Not surprisingly, they are now made in china.

Second one worked like a charm

These are fuses. They do what they're supposed to.
It's a fuse. It's relatively inexpensive and with Prime makes more sense than buying at the local auto parts shop. It blows out when there's too much juice or a short or whatever else makes a fuse blow. Really, it's a fuse. If you need this size and spec, buy it. Why do you need a review? :)

Works good for me
Swapped perfectly with the old burned out fuse I had. Quality seems good to me and I haven't had any issues with it.
