Long overdue, tired of fuses and it works perfectly

    • Quality
Style: 300Amp
Great product for the price. The plastic caps are fragile, possibly to melt if placed under the hood of a car. Overall I would purchase again.

    • Works better than fuses
Style: 300Amp
Works great. Trips at 3 seconds of 303 amps. At 305 drops to 1 second. Most don't think to test this but it is very important. Beats a fuse and of it goes bad in a year you can buy another and still be in a better position than with a fuse

    • Long time usage
Style: 300Amp
I’ve used this product for a very long time. I use it on my work vehicle and it does exactly what it’s supposed to do. I have multiple machines that I use it with as well as two large marine batteries so anything can go wrong and when it does it’ll let you know 100%.
