4.5/5 high quality, good bang for buck

The field of view is narrow if you're used to wider field single focal length eyepieces, but it's no problem to get used to. The construction is really good quality, and the quality is really great. I only found the view to be a little soft at either end of the zoom range, but otherwise really sharp. This eyepiece is heavy and big. When it's fully in the focuser, it can interfere with the thumb screw. The solution is easy, just use a smaller-radius thumb screw, or pull the eyepiece out slightly.
