Good product.
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!
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.
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.

Very good quality
This works very good, components are top notch, used as a master disconnect on an off grid solar system works perfect.

Good basic switch.
This is a good simple, marine or automotive grade switch. My only complaint is that it only has dust or water panels on three sides. The fourth side is left wide-open to dust or water sprayer. Whatever. Switches like this generally have all four sides and closed and you cut notches around the cables as tightly as possible to help keep out water and dust, etc., I returned the first one thinking there was something missing yet the second one came exactly the same with one side of the switch wide-open to the elements
