Rated 4 out of 5

CGEM1100EdgeHD

The scope's optics seem great. The views are fantastic. The mount seems to be more ten stable for visual. The controller quit after about 20min of use. After searching they seem to have trouble with the hand controllers. I rated the scope as very good despite the controller. If they take care of the problem in a timely manner I would raise the rating. If not I would avoid as they would not be trustworthy for other problems.
