I needed a waterproof junction box to use in conjunction with a sprinkler control line repair. The junction box was perfect for my needs. I was impressed with the seals and overall quality of the junction box until I came to screwing the lid on the box. The manufacturer included the cheapest screws I've ever seen. One of the screws lacked slots in the head and was useless! My recommendation to the manufacturer is to get rid of the cheap screwdriver included and spend the money on higher-quality screws.

Sturdy and includes several sized cable grommets to accommodate various guages of wire.

I have a Wyze V3 camera on my back fence and needed to power it from a source more than 50 feet away. Used a 12 v power plug in a 110 V outlet and ran outdoor lighting wire to this box next to the fence. Put a 12 v DC to 5VDC converter in the box, buried it in the yard next to the fence. Ran a flat a 6 foot USB cable out of it to the camera on the fence. The box is not visible and is safely buried away from people and dogs. I live in Phoenix Arizona and the heat gets to 114 and occasionally it rains enough to flood the yard. The DC to DC converter has not over heated (probably because it's buried more than a foot in the ground) and the box has not leaked to let in any water. Recommend this box for keeping power supplies dry in outdoor environments.

I couldn't find the sizes in the product description so I went by customer feedback. When I received the unit, it was way to small. I took measurements. Then I realized you can barely read the dimensions on the top in the picture. The outside dimensions are 5 1/4 " length X 2 3/4 " width. The length is measuring form the end of the cable screw to the other cable screw. The box itself outside dimensions are 3 " x 2 3/4 ". The inside dimensions (useful space) are 1 3/4 " x 2 5/8 ". I need interior space of 4.5 x 3.5. The unit itself looks okay - I returned it - but I didn't test for waterproof. The enclosed screw drive is standard, whereas the screws are phillips head. The screw take some effort to get in straight. The screw heads are not high quality and started deforming the first time I installed them. If these are going to be installed and forgotten, the screws are sufficient. If you are going to repeatedly open / close, you will need to get new screws.

Worked very well to splice an outdoor power cable for a septic system lift pump. The box is left above ground under a fake rock, so I have not tested the weatherproofing as well as some other applications might.

Used it in a marine application and it was excellent splice box for 3 conductors of #10 wire.
