Review: Perfect! - Exactly what I needed, very well made and plenty of sturdy protection. Clean look too, and mounting is easy.
Review: Good as always. - Sigma engineered parts are exactly what they say they are. Made from good materials, and reasonably heavy duty. This outdoor single-gang box is painted white. The paint is tough and survives some handling. After installation, it does seem weather proof, but only time will tell. Had to add silicone sealant to each of the plugs to ensure weatherproofing. Will buy again.

### ⭐⭐⭐⭐⭐ Great value, superb bargin
*by J***. on August 12, 2023*

I couldn't be happier with these electrical boxes. They are cheaper than other outlet boxes by almost 1/2. They have a nice appearance and come complete with all of the necessary hardware. I've purchased 3 of these boxes so far. I intend to buy more for the inside of my home as well. Highly recommended for its value and construction.
