Product is as described by seller. The meter is useful to measure electromagnetic fields and radio frequencies. The display is bright and shows all parameters in one screen including the alert levels as set by manufacturer or user. It uses 3 AAA batteries . The batteries generally are not sent with the product, as I assume due to aircraft cargo restrictions.
