Lynx Astro 2-inch Compression Ring

Bought to replace stock ring on my Sky-Watcher 72ED good quality replacement, threads good fit allows a more secure attachment for equipment. Good value and prevents damage to attachments.
Not too bad, not great either

Definitely a step up to the original visual back of the SW72ED, which has two screws. I hare screw marks so I wanted a non-marring visual back solution and this was it.
However, the screws really need to be turned on tight to ensure the compression ring clamps on the diagonal and if you use a diagonal like the Televue which has the infamous undercut, then there is some flex.
Will move on to a 2" Clicklock with M48 female connection and a M54x0.75 male to M48 male adapter.
