I have had a Falcon 4-18x44mm EMD2 from Frontier since July 2016. This scope is often the first to be used on all new picatinny enabled rifles and works rather well. Back then, there was nothing at the price that had those specs.
Given how the main-body and controls are the same, this is a design that has been around a long time, I'd say that it doesn't have much to improve. Eyebox on max magnification generates a very narrow field before getting the black morass, but that is the only complaint I can lodge.
I consider Falcon a budget tank.
