Really nice piece of work. My eyepieces feel much more secure with the brass ring holding them in place instead of a set screw. The thread for 2 filters is great as well, I have had no problems with any of my filters not threading properly.

Ive used numerous 2 to 1.25 adapters over the last few years and these are my favorite. Like all of Astro-Physics stuff, these are superbly designed, crafted, finished and anodized. The brass compression ring works very well and doesnt mar your eyepieces like a simple screw. Not sure how they could improve on this product.
