### ⭐⭐⭐⭐⭐ good quality box
*by M***U on September 15, 2025*

works very well my husband accidentally cut a Y electrical connector for garden lights, we look for a Y connector replacement but we couldn’t find any. this helped to fix the connector, its water proof very solid we below it’s going to last long time

### ⭐⭐⭐⭐⭐ Excellent junction box!
*by R***K on November 29, 2025*

Excellent junction box - very easy to install and it's held up nicely to the weather (rain and snow here in Wisconsin)

### ⭐⭐⭐⭐ Extras are nice, slight issue with quality of material
*by M***. on March 25, 2023*

This product proved unusable to me for the simple fact that the ports were 15mm and I needed to push a 19mm connection through. I cannot blame them for that, 1: they do provide a splicing port (I do not wish to cut my connectors off and splice) 2: I could have confirmed the size of the port vs connector beforehand Hopefully this review will help someone by encouraging them to double check the size of their wire+connector before ordering. However, I am going to remove a star because of the terrible screws and design for sealing the lid. The small screws are cheap metal and wallow out easily, and the hole intended to screw them into is too narrow, requiring significant force to screw them down tight (even pushing down hard, the screw heads wallow). This can be solved by using your own screws. I do appreciate the extra rubber gaskets they provided for potential different gauge wire, that was a nice touch!!
