Works as advertised but quality is lacking.
This works well, and has a variety of sizes which is very helpful when your car uses several different sizes (types) in the same fuse box. However, I found wildly inconsistent quality. The first tap I used had the end on the lead wire crushed so I couldn't insert anything into it. I ended up cutting the end off and splicing it. This is a recurring problem with generic parts like this, the quality varies wildly inside the package. In the end, I was able to use it and it saved me time since I did not have to splice the car's wires.

Best bang for the buck. True wire size.
Perfect solution for installing 12v accessories. I install equipment in many brand new vehicles for fleet companies and this product is perfect. The quality is great, they are affordable and fuses fit perfectly. The amount of actual wire inside the insulation is also proper. More often than not, other sellers push items with undersized wire gauge and with thicker insulation materials to make it visually look correct. Often times the amount of actual wire on these cheaper versions is not enough to carry the advertised current. I love that they ship quickly and are always available when needed.

KNOW WHAT TYPE OF ATO FUSES YOU HAVE
Works as described. Just make sure of your ATO fuse types such as mini, max or standard. Works great.

Decent, but stiff fuse holder
Overall decent item, but fuses are really tight to where I need to force them in and use pliers to pull them out. Fuses it comes with are cheap and probably won't last long.
