Works great
Works great for installing UniFi in-wall AP in a garage.

High quality justifies the price.
I have read a few negative reviews on both the single and double Surface Mount Backboxes, saying that they are too expensive. I disagree. If you are using just a few, the price is well worth the quality and beauty of the boxes. They are sturdy and well constructed. The back can be detached from the box to make it easier for several choices of attaching it to the wall. All four sides have interior markings for cutting to accommodate various types of wire raceways. It provides several options for securing the electrical wiring. Leviton outlets, switches, and faceplates fit perfectly. The backside of the box is slightly larger than the front, giving a somewhat artistic appearance. I am using several single and double boxes and could not be more satisfied. There are other less expensive brands of surface mount boxes on Amazon, but they look cheap and crude and belong in attics and basements. Leviton's boxes are suitable to be used in living spaces.

Back snaps on and off making this a easy install for a cramped space
I added an outlet inside a cabinet for so lighting. I was please to discover that the back snaps off the box, making it easy to work with. Mounted the back plate, hooked up the duplex then snapped the box back in place. Clean look since the only knock outs is in the back plate

Lifesaver
These were a lifesaver. I updated the switches and plugs on a house built in 1970. There were 3 outlets in a room, all a slightly different height, and buried partway in a shelf. I brought the wires forward , mounted these on top of the shelves and it looks so nice. I hate having to cut wall plates. Especially 3 different sizes. There are several holes in the back of the box, and I was able to find the right hole configuration for each one to mount securely to the holes in the electrical box. I had to make a couple of the holes larger, which wasn't a problem since these are plastic. And no visible exterior knockouts. More room and flexibility than a wiremold extension box.

Perfect for any job
Unlike other reviews I read, the punchouts were easy to remove and did not splinter or crack the box. I like that it has all the standard options available for different conduit and wire channels.

Comes apart when unplugging cord
Bought two, one of which comes apart when I unplug a cord. The back plate is attached to the surrounding walls with four snaps, and this somehow doesn't hold for me. I have a tamper resistant socket so there's some additional force but I don't think it should come apart like this. The other of the two I bought works perfectly fine

Does what it needs to do
I used this for an Ethernet cable with faceplate. Worked great.
