Review on EPAuto 12V-DC ATC/ATO 12 AWG In-Line Fuse Holder - 10 Pack (30A) by Philip Brianne

As others have complained, the fuses are difficult to insert. As the song says, "You'll need a little patience." back and forth one at a time, being careful as you do so. It'll take a minute, but everything will be fine. I'd rather it be nice and tight than just fall out, right? If you're really impatient, you can just stick a small flathead screwdriver inside. If you do, chances are you'll open it too wide or slip and poke your hand with a screwdriver, no fun right? Just take your time and you'll be fine. You'll know when it's fully seated because the lid won't snap if it sticks out too far and the fuse won't be flush. Not to mention your circuit is probably not working or only working intermittently. Also, I don't care if they're made in China, the North Pole, or Mars, they're a quality product. In conclusion, to refute other reviews. Each piece of wire is 10 gauge, not 12 gauge, not 14 gauge and certainly not 8 gauge but 10 gauge. Peel off the sheath and tuck into the gauge wire and you will see that it fits snugly and snugly on the 10 gauge wire as indicated. You can easily run 30 amps through them as promised. If the fuse keeps blowing then you are obviously trying to increase the amperage or you have a fault in your circuit.
