Title: Doesn't Do the Job
Review: I have been doing biofeedback for many years. This is not a true biofeedback device. Biofeedback is using a device to discover what you feel in your body when, in the case of a temperature device, you see the temperature change on the device. This device is not sensitive enough to do that. Also, this device comes with NO relevant instructions. Don't waste your money.
