MAS 5 Pcs 20 Amp Large Blade Style Maxi Fuse for Car RV Boat Auto (12V only)

DO NOT BUY!!! These Fuses are complete garbage. I purchased 30A fuses, they were marked as 30A fuses, but looked more like 10A fuses. The load they were protecting is 22A. All five of these blew within 5 minutes of being installed, and melted the packaging. The last one even damaged my fuse holder. I had to buy a 30A Littlefuse replacement on the road, and it is still working just fine after several hours.

These fuses are not actually 80 amp as labeled. We spent a considerable amount of time investigating why our 50 amp resetting breaker was failing and blowing this 80 amp fuse. Turns out that these 80 amp fuses were the problem. These fuses were less than 50 actual amps. We lost a lot of money tracing the problem. Shame on me for buying the least expensive fuses

I have had these fuses in place for about 3 months, then started to have some issues with the "protected" electronics. I was surprised when I discovered the melted fuse housing. The fuse never blew but apparently the heat was apparently significant.I don't think the risk of getting a bad fuse is worth the risk.

I had to give everything a one star regardless of easily install or not. These things blow quick! Buy 1 good quality fuse and it will last longer than a pack of these. I promise you! I live in the desert and these blew at least once a week if not more. I bought a good quality fuse and haven’t changed it in 4 months.

Blades are not parallel. They're instead both bent outward, like the letter 'V' (on all five 30 amp fuses). They work, but they don't fit well. Takes a bit of bending.
