Decent build quality. Not exactly sure what it is measuring because it is very erratic and sometimes the readings spike just because you move it. Registers when you hold it near an appliance, wall outlet, etc. If you need a cheap proximity meter to see if there is electricity present, the price is right.

Good basic emf reader, we were surprised how much emf came from laptops and extension cords.

Easy to use. Not a high tech meter but it does the job. And it was very affordable...fast shipping, too.

This is bad imitation product from China. Did not mesure any radiation or electro magnetic device unless you are very close to the device. It should be mesure from any distance to see which any radiation is around.
