Title: Super strong material
Review: This thing feels almost indestructible, the plastic is incredibly tough, yet has a bit of flex so it wont crack like the other brand i tried, before going this route. I will be buying more of these for future projects, where i need a tough fuse that can withstand the elements.

Title: Perfect for RV
Review: Using for 2000w inverter in an RV. Perfect straight forward and simple solution and the insulator caps are a great added bonus. Replaced 250a circuit breaker which caused intermittent problems with current flowing back to charge the batteries. Great value.

Title: Thick, heavy duty, and looks great!
Review: I really like this product! It’s very strong and thick and durable. I used it on my 64 Thunderbird to fuse my alternator charge cable to the battery. I did not use the fuse that came with it. I used a 200 amp fuse as I have a 173 amp rated alternator. I only gave it two stars on water resistance because it it doesn’t really have a cover. However my application does not need to be very water resistant. I think it worked great! I will be buying more for future projects.
