Not for Australia / New Zealand
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.

They work
Did a really nice job using these alot better then trying to measure and cut them out that way.

Much better than measuring
Excellent. Makes marking boxes pretty much full proof. Just make sure to pay attention to the arrows for orientation. Used on drywall and OSB. 50+ boxes and counting. Highly recommended.

Très bon produit.
J'ai pas le compas dans l'oeuil et mes ouvertures dans la plaque au plâtre était plus souvent qu'autrement aproximatives. On rénove notre sous sol et on gagne énormément de temp avec cet outil. c'est incroyablement simple et efficace. Je recommande a tous castor bricolleur. Ceci dit, même si c'est conçu pour des boitier en plastique ça fonctionne aussi avec les boitier en metal.

If you want precise cutting locations this is the tool you need!
At first I thought this would just be another run of the mill tools that you would discard in your toll box and forget about it. No, no, no, this Drywall Electrical Box Locator Tool made my job so easy it cut my job by a wide margin. And don't waste your time on any other tool for cutting the sheet rock just use a box cutter fast and easy. bada bing, bada boom your done. Word of advise! when tracing your mark allow at least 1/8" inch more around your cut. It's so easy a cave man can do it.
