Query: Completely Inaccurate

We had the NYC Department of Environmental Protection come out to our apartment because we were highly concerned about the EMF's in our kitchen, as indicated by the Trifield 100XE meter we just bought. Their professional equipment proved this meter to be entirely inaccurate, and more like a joke. We looked so amateur with our little meter and felt bad we brought the guys out based on a reading from a cheap device. Better safe than sorry, but it certainly would have abated our concerns from the start had the meter been accurate. We could have received a faulty meter, but there was no way of knowing until the professionals came to prove otherwise. We are sending it back, but evidently we will not get a full refund because it is outside 30 days.
