Review: Awesome outlet box, works perfectly! - Love the two angled screws! This box is amazing in my view!
Review: Neat retrofit alternative (vs. "wings" design) - Compared to a wing-type retrofit box... WING Pros: easy to place (anywhere, no stud needed), easy to install (cut hole, insert into wall, turn screws to open and clamp wings against wall). Slightly cheaper/wide availability. Cons: flimsy, can feel attached items flex; depending on stud spacing and wall quality, may flex (or if you're clumsy) crack a wall area. Have to be careful with steps like breaking open stubborn new wire tabs or torquing down objects to the box to avoid damaging weak wall. THIS Pros: Sturdy install! As good as -- in fact, probably better than (screws vs nails) -- original build boxes that usually are also attached sideways to a stud. This particular product also has a nice thick frame, box itself is strong. They did a clever job allowing you to access the install screws with as little impact to space as possible. Cons: Harder, or at least less convenient, to place because you need a stud/crossbeam, and have to cut your hole more precisely so the edge of it is on a stud. Harder to level the box if your studs are super-crooked (though most final devices allow leveling adjustments so shouldn't be an issue for most situations). Slightly less interior space than some wing designs. Right/left sides of box may end up uneven since screws can cause opposite side to slightly pull in deeper during tightening, worse if your stud is twisted -- a little extra bracing or plastic nubs at the back edge of the box would help prevent this. OVERALL Unless there's an issue with stud spacing, I plan to use these going forward. These are as sturdy as original build quality and will last no matter what accidents happen around the box, yet easy to install and fine pricing for one-off house projects. I have enough practice with stud finding and hole cutting to get nice holes cut alongside studs -- wing design might be better if you're new to it.

### ⭐⭐⭐⭐ Great box for old work.
*by B***. on December 7, 2024*

Bought this because I had to add a new outlet and accidentally cut the hole in the drywall too big. Because one side of the hole was against a stud, this worked perfectly to secure in the hole where a standard old work box with flanges that didn't have anything to grab onto. I bought the one that was extra deep, plenty of room for three sets of wires coming in. The box itself is very sturdy too. I did take off one star because the tabs in the back are difficult to remove and they leave behind a triangle that can make it hard to feed the wires past. Just a note, I'm a DIY homeowner and I only had needle nose pliers to get the tabs out. So for more experienced folks with better tools it might be easier.
