I spent sometime reviewing a number of Diagonals to replace my standard issue 1.25 Celestron one, which came with my Nextstar SLT 6" SCT. Really in the end, I kind of narrowed it down to a Celestron "Twist-Lock", Tele-Vue or WO DURA-BRIGHT.
Well, I could have spent over £50 or more on the Tele-Vue, but when I ordered and received the WO DURA-BRIGHT (very nicely packed by FLO) I was very impressed!! Firstly, if you compare your Diagonal which was supplied with your Scope, (just look through it with your eyeball) with the DURA-BRIGHT, the difference is blatantly OBVIOUS. The Image is Bright and has More Contrast. The Build Quality is very good, and I had NO problems extracting my Celestron X-Cel LX eyepieces (some people mentioned issues with the compression ring, binding on the eyepiece undercut, with this type of locking system, which is used by several manufacturers by the way) all I can say is, I haven't found any Problem as such, just don't over tighten the locking Screw, and a very slight lift and wiggle, as you extract the eyepiece, if you ever find it necessary I suppose.).
So good I purchased this twice!

When I purchased my Tak 76 in 2016, I needed a high quality diagonal to go with it; I travel a lot so only use 1.25 eyepieces, Ian King had sold out of the Tak prisms, and suggested that this was a great quality diagonal. It's been superb, traveled lots with it, used extensively at Seething, the Astro Camp and the Astro Fam in Confolens for a Messier Marathon...Sadly, I managed to break my original in the early hours of one morning. FLO was the first website I went to, to replace it. High quality, lightweight and well made; holds my 24mm Panoptic and 9mm Nagler with ease, has a compression ring (i think that's the term) so you don't make marks onto the barrel of the eyepieces. The barrel that you insert into the telescope will unscrew, which is perfect for helping you blow away any dust that will accumulate after many uses...Has a 2 year guarantee, and unless you're a "butterfingers" should last a long time!

As soon as I took my Celestron Edge telescope out of it's box I knew I wanted to upgrade certain items. I'm just like that... This diagonal looked the part on the website and face to face it does not disappoint. Excellent build quality and superb looking clear mirror. The fixing look more substantial too. I am fully trusting this to hold my Vixen eyepieces and to look good while doing it. Recommended !!

Great product, great service! But I wish they'd stop asking for feedback every time I buy something!!

This diagonal looks good and feels even better. Compared with a stock Skywatcher diagnoal, the build quality is far superior. I used this diagonal with a Celestron X-Cel LX (25 mm) and the view was crisp and flat to the very edge of the FOV.

People look at this diagonal and assume that - due to its hefty build - it must be of high quality.
Unfortunately it has two problems which are serious enough to strike it off your wish list:
1) Firstly, the internal safety-stop actually obstructs light - vignetting the edge-of-field on super-wide eyepieces.
2) The safety-stop - and some other parts - have shiny surfaces which casts glancing light reflections into the eyepiece, causing annoying glare on the moon and bright stars.
Best choose something else.
