The fuses came in a 10 pack for future replacements. They are a great value for the price, and now I have some to cover possible blown fuses in the future. Glad I bought them and they get 5 stars.

### ⭐⭐⭐⭐⭐ Perfect fit!
*by M***. on May 4, 2024*

I ordered these fuses for my electronics like DVD and CD players. My DVD player (2 years old) wouldn't turn on after my power was restored after a storm. Most people would have just thrown the DVD player away. Not me. I opened the DVD unit up, and like any small electronic device, it has a a 250V slow blow fuse to protect it from frying when there is a power surge. I pulled the fuse and checked it with my multimeter for continuity, and the fuse was bad. I ordered these fuses and installed one into my DVD player and it fired right up after plugging it back into the power grid. These fuses were a perfect match. The price was right too!
