This is fantastic! I used this to cut out outlet holes in our wall panels and it worked perfectly! The magnets are super strong and we were able to identify where to cut holes in the panelingThe packaging of this product is also great!

This review is for homeowners or DIY'ers. I bought this for a home renovation project where I have 38 receptacle boxes to cut drywall around. I took a little extra time with the first couple to ensure accurate alignment and reliability. There is a small amount of play but once I got the hang of the positioning I was happy. The magnets work pretty well on 1/2" (12.7mm) thick lite drywall although I'd suspect it not being great for 5/8" (just a guess). I'm not in a hurry so taking the extra time to position these for a nice fit worked well for me. Yes, it's slower than a Rotozip but I like having a better fit and mudding less. If you only have a few boxes to cut out then it's probably not worth it. I had a variety of receptacle boxes from both Home Depot and Lowes, some thick, thin, deep, shallow, etc. and these fit them all. I even used it on a round light box. To that, I drew the line around the box and then diagonals from the corners to find the center to drill the hole. Would be great if both pieces had a 3/8" hole in the center for drilling light boxes but I know they sell another version for that instead.

This thing works great!!Takes the measuring and guesswork out of putting in outlets. Perfect hole for an outlet or switch box every single time!! Put the one smaller magnet in the outlet or switch, put up the sheet of drywall, then the outer magnet snaps right into place, trace it, and cut the outlet /switch hole.Very handy tool!!

Sometimes I'm skeptical of "tools" like this which seem to be approaching a gimmick. I had a very complicated drywall replacement of an old backsplash above a counter top that had three outlets on it. This tool worked its magic like a freshly sharpened knife used to slice ripe tomatoes. One suggestion I have is that if your studs (and thus boxes) are level, when you place the outer magnet square on the drywall to trace your outlet box, put a torpedo level on top of it and ensure its level before tracing around it. Overall I did four cuts for four outlets with my first use of the tool and it worked as advertised. I highly recommend it. If it saves you one 4x12 sheet of drywall, it's already paid for itself.

This product works as described. The only issues I've encountered are that I used it incorrectly once (arrows down instead of up) and once I forgot that I had placed a marker behind a sheet of drywall. The only issue that wasn't user error is that he pins that load into the threaded screw holes are very tight in metal boxes. I tried to crimp one with pliers so it would slide in better, but it broke the pin, that marker still works, though. Other than that, this is a worthy tool, easily made my money back in a day through the efficiency gains of not having to measure out electrical boxes.

I stumbled across these on here and decided to give them a go! I got to say I am so glad I did! I am by no means an expert but these made cutting outlets in the drywall sooooo easy! It takes a little getting used to finding the perfect fit but you soon learn the little wiggle that sets it perfect!TRY THEM!!!

This things works great. Made hanging drywall with switches and outlet boxes so easy. Just don't have the switches installed first. Works on empty boxes. Fits great and gives great box marking for hole cutting.

Works well, but not as useful as imagined. They don't like to stay inserted in the receptacles that already have wire runto them. Which is most receptacles.

I had to cut sockets in OSB (not drywall), and this tool helped me a lot. No measurements and no taking the sheet off the wall. Depending on the socket type and your cutting tool, you may be hitting that thin wire that inserts into the socket hole. So far it held up but I think in my case the lifetime will be limited. Given the price that might be fine.

Fantastic! This made box cutouts on drywall and OSB a snap. As others have noted, the traced box tends to be a bit big (see photo), but still easily covered by the outlet cover and easy to adjust for further cutouts. Line up the magnets, double check that both sets of magnets have engaged, trace, and cut. No more measuring and fiddling. Perfect for the weekend reno-warrior like me.

Very simple product that does its job.Make sure the finder magnet is right on top of the box magnet,you can wiggle it a bit to feel the strength of the connection.There be probably a few mm play to it but that ok the outlet cover will hide it.When cutting the drywall make sure to cut it a tad on the outer marked outline not on the line itself so you can fit it over the box.

These looked great and would be a handy addition if your putting up your own drywall/gyprock in the USA. I got them but they do not fit the AU/NZ size standard size wall plates. I returned them with no issues. Bummer! The magnets seemed pretty strong to me.
