Although the cost seemed high the mount was easy to install, easy to adjust, functions flawlessly, and provides great flexibility. The adjustments are firm and I have not experienced any sagging or tilting as otehr reviewers mentioned. I did not use the provided lag bolts because of special mounting contitions so the issues other reviewrs mentioned regarding poor quality hardware did not affect me. After installing it and using it for a little while I realize that it was worth the extra money for the flexibility that it provides.
