Good gang boxes and easy to mount.
These are decent single gang boxes. I use them in conjunction with water proof outdoor outlet covers. Easy to work with and mount. Water proof? Don't know, I'm not spraying water on an electrical outlet to find out either. LOL After a little rain, they seem to always be dry.

4.5/5, Worked perfect for the project.
I needed a box with a back inlet to surface mount to a deck joist. Size was good. Meets Code for weatherproof. I had no problem installing a GFCI receptacle to 12-2 UF cable with ground through the back inlet. I didn't use the supplied screws and got #10 × 1" stainless screws to mount it. Do NOT use a drill or impact to tighten the mounting screws or you will likely crack a mounting ear. Even being careful, I cracked one ear and had to throw it away and start over with a second box. Do the final tightening with a screwdriver. Installation tips to use the back inlet: I used the bushing to reduce the back inlet to 1/2" conduit and glued it in with Oatey Medium Gray PVC Cement. Then flush cut it to the back of the box by hand. Threaded 1/2" conduit to fit the bushing. This allowed for a smaller hole through the joist. (If you want to thread nonmetallic conduit, push a drill bit slightly larger than the conduit I.D. into the conduit and use a pipe threader or die. Clean the threader every full turn for clean threads.) Glue in the conduit and the plugs for the holes not used. To comfortably fit the GFCI, push the wire flat to the back of the box with electrical pliers. My area requires an in-use cover to pass Code.
