I bought the 180x and 300x lenses. With the 180x lens, this scope is really excellent value. The 11.6" screen has good clear picture. The camera produces high quality images even at 3x digital zoom which is very handy. I DON'T recommend getting the 300x lens. It is relatively bad and not really usable at 300x. There is a lot of color aberration and the images are foggy. I think this really long lens really needs some baffles installed in the tube in order to make it usable. Or maybe I just got a defective lens? Don't know. But that's why I took off a star. I use only the 180x lens now which is excellent.
Working great but I need to increase working distance somehow and the manual white balance settings are reset each time you exit the menu or change mode which is annoying.
