Disappointed
Bad: What I was looking for was something that I could use to scan EMF and provide a LOUD alarm when levels were in a range that would interfere with a defibrillator implant. An employee with an ICD walking through an industrial plant, for example, would need to know if they are in an area that is dangerous to them. But industrial plants are loud, and employees will not be able to hear the quiet chirping alarm of this device over all the noise. (The alarm also sounds at very low levels and is not programmable to a level which is remotely closer to the actual threat level).Bad: I would expect a device that costs over $300 would have a rechargeable battery, instead of using AAA batteries that have the life of 8 hours. If this device is going to accompany an industrial employee with an ICD, the cost of battery replacements will be very costly over time.Good: I like the pocket size of the device.Good: I like that it measures not only electric fields, but magnetic fields as well.

Handful tool
Easy to use. Handful to illustrate the field that we are exposed to. Helpful to explain standards.
