## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product.
*by R***4 on July 1, 2026*

I bought this one and a cheaper one. Buy the cheaper on. Except for being a darket color and having a name on it they both are identical

### ⭐⭐⭐⭐⭐ Works as advertised!
*by B***Z on July 1, 2026*

Does what it is supposed to do. I am using 2/0 cable and had to trim the case a bit to make them fit. so make sure your wire and lugs are smaller than 2/0 or trimming will be necessary.

### ⭐⭐⭐⭐⭐ Solid, durable and built to last.
*by R***S on January 19, 2026*

Used this on a travel trailer and installed it right on the battery box. Was easy to wire in and seems well made and durable. Connection posts are solid. I think this will hold up to the elements and is a good protection for my trailer. I did need to buy a different set of nuts and bolts for my specific application, but that was expected.
