I've looked at many reviews on items like this and it seems everyone agrees that the functionality of the magnetic field detector is very sensitive and I find that very true as I have it tested. The machine measures multiple planes at the same time rather than a single patch (other cheaper machines do), giving you faster readings. I think this meter is a very reasonable entry-level device to give you a very good idea of the magnetic fields around you (as well as radio waves and electric fields, albeit less accurate as many other online reviews say). It's not cheap, but if you're looking for a home, it's a really great tool to have on hand.
