A well-worthwhile upgrade
I swapped the MeadeLX-600 visual back for the Baader ClickLock adapter at the same time as acquiring their 2" diagonal. (The former needed a few turns of PTFE tape to marry the threads to the OTA but now feels firm.) The diagonal is quite a piece of engineering and a joy to behold. The locking mechanism is genius. I will hold onto this for life. Clever chaps at Baader. Full marks to German design and manufacture.

Just short of excellent
Generally well engineered and beautifully constructed, competently suited to its purpose, but with what seems to me to be a questionable design decision – both the eyepiece chuck and the focuser tube thread into the prism housing and are held in place only by friction. When pressure is applied to the locking lever to unlock the eyepiece, the torque tries to unscrew the chuck from the prism housing. Similarly, when the diagonal with a heavy eyepiece is angled off to the left in the focuser, the torque threatens to unscrew the prism housing from the tube that is held in the focuser. I’m having to consciously take as much care as I did with a conventional thumbscrew diagonal! Can’t this be improved on? I’m busily looking for my bottle of Loctite.

Great build quality
This diagonal is a significant upgrade from my previous SCT only diagonal. Using it with a virtual view visual back allowing free rotation, and the ability to thread a filter on the diagonal.
