Very useful, just what i needed..
Fast, good prices and knowledgable staff. What more could you ask?
I wanted something moderately priced that had a wide-ish field of view and enough eye relief for glasses. This Celestron EP hit the nail on the head. Eye relief is sufficient (just) for glasses wearers. Sharpness has been great. Field of view is not spacewalk wide but I wasn't after that so it has been just fine. Having this eyepiece be parafocal with the others in the set is an added plus. I'm sure other more expensive eyepieces are "better" but I'm very happy with the price/performance trade off of the X-Cel.
