Review: You can't go wrong with Blue Sea! - After upgrading the alternator on our vintage RV we needed some stout wiring and a much larger fuse, enter Blue Sea 5001 and a Blue Sea 200 amp fuse. As usual, install was super easy, and I cannot see any issues with the lasting forever! Blue Sea stuff is super high quality and we have used it all over our RV. In the image there are two other Blue Sea products! For the price this is perfect!
Review: Quality. Lid stays on - Works! I had to put a mega fuse on it and connect it up to my lithium solar configuration in a tight space. I went with the name brand because the lid stays put. The knockoffs don't. Thanks Blue Sea

### ⭐⭐⭐⭐⭐ Great Quality and fast shipping
*by N***K on June 28, 2024*

This was a VERY good buy and really tight sturdy fuse highly recommended!!!! {UPDATE} After some time under the hood of my car the plastic or base of the block started braking apart like shattering away now allowing the block to slap around. Not good for anything outside of the cabin of vehicle.
