Saved me for a cheap price. And saved money by not having to get a mechanic.
Lifesaver for me. My car suddenly totally quit on me and left me stranded. Had it towed home until I could decide what to do. Saw another guy who had the same problem and he said this fixed his problem. My car would not start at all, no click, no nothing. Bought this fuse and installed it myself. Car started right up. Couldn't believe I fixed it my self for such a cheap part and didn't have to have it towed to the shop.

They fit the MEGA fuse holder in my van perfectly.
They fit the MEGA fuse holder in my van perfectly. Used as main fuse from a Transit seat base CCP2, to a Renogy 1,000 watt PSW inverter, have had no problems. 150 A is just enough to cover the max rated surge draw on that inverter. Not enough load in this van to pull that much current, I may never need the two spares, but having at least one on hand is always recommended.

Good fuses
I was helping out a friend who owns a limo company and needed some specific fuses for one of the limo busses after having to add in some new wiring after the factory harness rubbed thru on the front crossmember. As long as you have the right holder and are using the correct amperage fuses these should work just fine.
