## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent Quality
*by L***G on July 22, 2025*

I am amazed at the quality of this little box.. First off, all the parts are included-nothing missing. Next up, everything for including the seals. Excellent product at a fair price.

### ⭐⭐⭐⭐⭐ Great product and inexpensive
*by R***. on July 13, 2025*

These are actually pretty handy and inexpensive for what they are. They come with everything you need. I don’t use the terminal block that comes with it but I’m sure it’s fine.

### ⭐⭐⭐⭐ Cheap, but not too cheap. Supply your own terminal strip though (replace what it comes with)
*by D***N on October 16, 2025*

The busbar screw terminal thing it comes with is cheap, and the lid does have a gasket but it's thin. It does come with multiple glands for larger wire sizes, but not anything thinner than 18AWG (and that's still pushing it). HOWEVER, this gets high marks because I used it to splice in tail lights on a car hitch lift, and it has survived driving through deep puddles at speed (not submerged), heavy downpours, and being out in the Florida heat. I haven't had this for a full summer season, and this will be the first winter in the North. I took the extra precaution of RTV silicone over the wires at the glands, some wire loom tape over the outside connectors, and dielectric grease over the terminal strip that I supplied myself. We'll see how it does long term.
