I doubt a review would help...but.
It works, I mean its been machined to do exactly what itâ€™s supposed to.
The ring mounts firmly on my Canon 20D and threads to whatever mount you need it to thread to (provided the thread pitch and diameter match).
It appears to be made from two pieces of material. The outer ring which mounts to the camera and the inner ring which I assume Meade uses for other T-Ring adapters.
Iâ€™ve owned two in the last 10 years, one for a former Pentax 35mm and my current Canon 20D. Neither had failed or gave me any problems. It has a dot for alignment for a reason, donâ€™t force it or try â€œfeelingâ€ around in the dark by rotating it until it locks in, youâ€™ll only damage something.
If youâ€™re looking for a good match to your Canon (EOS type camera), I suggest you try this out.
