I had the Novagrade and returned it as well. I found it to be a PITA to get lined up right as compared with others. I ended up with the tinesup. Works great.I had the Novograde and returned it - does not work well with binoculars. Slips off quite easily. I can see how it works well with spotters with those larger eye pieces but seek other options if you are considering binocular use only.
