It does the job it's supposed to do. The only down side is the connectors are a bit thinner than I expected and have plastic insulation instead of heat shrinks, but you can always just change the connectors to better quality ones.

I installed this on my sons power wheels and it works great. Only downside is that when it does what it is designed to do (break the circuit) it resets immediately. My son being 5 years old didnt know what the power wheels stopped and kept his foot on the pedal and burned out the motor that was causing the fuse to break in the first place.
