## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent Enclosure
*by D***L on February 5, 2026*

Well made, heavy construction, plastic is thicker than expected, well pleased. Has 2 clips inside the lid that aren't explained and don't appear to do anything..

### ⭐⭐⭐⭐⭐ Good value
*by K***N on December 25, 2025*

Works great. I will never get the cover on this.

### ⭐⭐⭐⭐ Quality not as good as a Bue Sea product, but is good enough, good form factor
*by J***S on April 7, 2025*

Quality is a little sub par when compared to Blue Sea, but it is a product I will install. I bought this looking for a more compact/dense bus bar than Blue Sea sells, ideally with only a single large stud - the way this one comes is a good form factor. Quality wise specifically, the main stud is loose and is secured with a nut on the top, and then another nut on that stud actually secures your wire lug that feeds it. The plastic is a little cheap, screws are a little cheap, again, as compared to Blue Sea (which is a high-quality brand).
