At the discounted price, there wasn’t much to lose and I have to say I’m very impressed. It’s reasonably light but still well made, the zoom is very smooth and the eye relief ok. Although the field of view gets smaller at lower magnification, it’s acceptable and the clarity of view and contrast seems good. It was cheaper than most nasty single focal length eyepieces but much better. I’ll definitely use it with my travel scope and possibly with my other scopes. Review: Well made and clear optics. - This is a really handy EP to have in your kit. Clear optics and a decent zoom range, and good eye-relief. Well built and 'feels good' in the hand and while using the zoom.
