This is certainly a convenient jig for helping to quickly locate where your boxes are so you can cut openings in your drywall. It takes very little time to put into place and stays out of the way while you're hanging your sheet. The targets pop right onto the drywall and you've got a good sense of where your box is located.
This is where things come up a little bit short. First, there's friction on the drywall so the magnet doesn't line up perfectly with the box underneath. It gets close but it can be rotated by a few degrees and so you're not quite sure exactly where the edges of your boxes are. That's annoying and it makes this less than perfectly accurate.
The other issue was my fault for not reading the instructions closely enough. I will completely admit that I've only done a couple of projects with drywall so I'm in the beginner camp. Well I plunged my rotozip bit right on the line I drew but that ended up hitting the box side and I ended up plunging inside the box and getting a bit tangled up. It turns out that the line is basically on or very slightly outside the underlying box so you should plunge just outside the line and move your ways inward to trace the outside of the box. You can see in my results picture that I didn't end with the cleanest cutout.
Long story short I was hoping this would simplify things a bit more than it did. I'm sure with a bit more practice I'd get more confident. Or alternatively if I used an oscillating tool I probably would have gotten cleaner lines than the rotozip. In any case perhaps my expectations were too high but this one strikes me as being a bit of an imprecise gadget rather than an indispensable tool.

This is an ingenious little device. As many other reviewers have stated, cutting drywall for electric boxes is a time-consuming pain for the average DIY. I am no different than most, and have tried almost everything (lipstick, nails protruding from the box, measuring tape, etc.). And while I love using a Roto-Zip tool for this type of job, who hasn’t made a mess of a plastic box? This product works very nicely, and it’s close to perfect.
The tool set consists of 3 “targets” (square magnetized blocks that fit into a standard electrical outlet/switch box) and 1 “locator” (a square magnetized block that will line up with the target that is hidden behind the drywall. Each of these blocks has two magnets with different “poles” meaning that each magnet will only gravitate toward the magnets on the other side of the drywall, that is the opposite pole. This means that the blocks will line up “almost” perfectly with each other, essentially making it impossible to goof by placing the locator upside down. In fact, I tried to place the “locator” upside down and it was repelled by the target magnet (simple concept, ingenious application).
When I say the product is “almost” perfect, it is because, if the target and the locator are not both plumb, it is possible that the “locator” will not line up exactly with the real location of the target (see picture), it may be off-plumb by several degrees. Before using the device for the very first time, it may be worthwhile to set the target and the locator near the edge of your sheet rock and place the target slightly off plumb to see how it works.
One last comment – these magnets are SUPER strong. If you are holding them with your fingers, take care not to bring the locator and the target close together, as they can snap together quickly and pinch your skin.

This product really makes it easy to locate receptacles when installing drywall. It saves time and has even caught the attention of other contractors when I have used it.

For years and years I've been doing construction and renovation jobs for my business, family and friends. Doing proper cutouts in wallboard for switches, outlets and light fixtures is a time consuming exercise in the ability to take accurate measurements. It's all too easy to get distracted and ruin a sheet.
I spotted this very ingenious tool on HD's site. The one major drawback for me was that the outlet or switch has to be removed from the box to use it. It's perfect for new construction, before the outlets and switches are installed but the time it takes to empty and refill the boxes kind of negates the time saving factor for renovations.
With no projects currently in the works I decided to test its accuracy by nailing a new box to a 2x4, inserting one of the three targets included and screwing a scrap of wallboard on top. The locator snapped to the board instantly but something didn't seem right. Sure enough, when I looked behind the board the top magnet of the locator was attached to the bottom magnet of the target. I discovered there are two simple solutions to identify this when it happens in the field. One is to take a measurement from the center of the box to the floor before starting the install or, a quicker way, is to twist the locator. If it's set on both magnets it will resist the twist. If it's attached to only one magnet it will twist easily. I corrected the problem, outlined the locator and went to work with my Roto-Zip. Staying just outside the line I cut three sides quickly but the fourth side, next to the stud, caused a problem. The bit wouldn't go in deep enough to cut the wallboard. In their video their box is not touching the stud so the bit has clearance all the way around. For me, not a deal breaker, I used my multi-tool for the final cut. The cutout was perfect. No need for Midway or Jumbo plates. This will be my "Go To" tool for new construction.
While perusing Blind Marks web site I noticed they have a box locator set for renovations which doesn't require outlets to be removed. Won't work for switches. It's their model 8120. Images 2 and 3 below show this product.
Blind Mark includes a one year limited warranty on this product.

This is a great tool to have around the house if you have drywall projects.
The tool is very easy to use and very accurate. I am not a drywall guy by any stretch of the imagination and usually I end up butchering the sheetrock when I am finished. Not with this tool.
Now using this tool everyone can have professional looking cuts around switch and outlet boxes;
Keep in mind though that this is for new construction with no wires in the box for room for the magnet to sit in the box.
A good tool for cutting holes in sheetrock for the guy that's not a carpenter. I recommend this tool.

Rated 5.0 out of 5.0 by bhcdiy OMG--- This is the Greatest TOOL!
This is the neatest tool I have run across in quite a while-- It is very simple to use,good clear instructions and makes life SO much easier when trying to cut the electrical outlets in so many different applications of products. I have used all kinds of gadgets to mark the box (lipstick,nails,tacks,etc) in the many years I have done jobs and NOTHING is as great as this tool! When I showed this to a friend of mine who has been a carpenter for years, he was so impressed he ordered one from HD right away and uses it all the time in his jobs now. Any professional OR DIYer needs this kit for sure!!

I wish I had the Drywall Electrical Box Locating Tool Kit when I was building out my basement, it cuts out a lot of guess work when I was installing the drywall because of it's magnet system. I would recommend to disconnect the power to the room that you are working though if you are using in an existing if it already has outlets installed to eliminate shocks...

Rated 5.0 out of 5.0 by Jayhawkfan Great product that saves time
This is a great product that allows you to have perfect electrical cutouts in drywall, paneling, or thin plywood. The final product is a perfect cut every time with no measuring. Place the base magnet in the outlet then cover the outlet with the finish wall covering drywall or paneling, then attach the top magnet on top of the drywall and it will stick to the base magnet, trace around the top magnet, then cutout and you have a finished electoral box the is completely perfect. It works with any size electrical box to produce perfect cutouts every time with zero measuring. Love this product. Great time saver.
