My reasons for acquiring DPE 100 was firstly for providing environmental balance and protection.
There has been an increase in bird activity, leaves on all trees and shrubs are healthier looking, and the occasional Monarch butterfly hovers over the device. Also, the mosquitoes have not been as prevalent as they used to be. Other than that, l do not have any before and after points of reference to compare against, such as extreme weather conditions being less so or energetic interferences.
Kind regards, John.
