romeox seems to be the highest quality available, I have both a romeoX and Holosun EPS-C on different P365s, I prefer the controls on the romeo, and i trust the quality more(I've had 3 holosun lenses pop out over the years, all taken care of under warranty) I just wish the Romeo was enclosed, but it's not a deal breaker.
I tried the Holosun 407k and the lens was super blue and distorted at the edges, the EPS doesnt have that problem, and neither does the romeo. if that matters
