I bought this to replace the plastic mount supplied with Celestron's 15x70 Skymaster Binoculars. The Celestron mount supplied is not particular robust (it is made from plastic, probably polycarbonate.) When using it, the binoculars oscillate from side to side and take quite a time to settle down, making it not particularly good for viewing the sky (the binoculars themselves are excellent quality for the price.)
This metal mount is more robust, the degree of oscillation is less, and the oscillation dampens down much more quickly. In my opinion, it makes the binoculars far more usable for sky viewing with a tripod.
It would be good if Celestron supplied a better quality mount with their binoculars.
Until they do, I'd recommend this as a good replacement.
Note added three months later;
Before you buy; Check the screw thread size of the mounting bush on your binoculars. This mount fits my Celestron 15x70 (bought in March 2013), but it doesn't appear to fit all binoculars (one example; a Celestron 15x70, bought in 2005). Also, see two examples of negative feedback in reviews below over thread size being incorrect for other binoculars. However, most customers are very happy, as am I.
