Sorry
I am truly sorry to report that I am not enjoying my purchase of the Zhumell 20x80 binoculars. No fault of Telescopesplus, but they came to me out o collimation. It took 4 days for Celestron to contact me after I had emailed them describing the problem, two images that could not be adjusted out. So finally after emailing back and forth, the representative with Celestron agree to waive the warranty fee o $14.95 and created a return label for me to return them to Celestron, I learned that Celestron own Zhumell, anyway they just received them today and will be sending me another pair to replace them. They tell me their team will check the replacements to assure they are collimated. Maybe when I finally get them I can post a better review, but for now this is about all I can report. Rodney Snyder
