These beauty rings are great for what they are and wholly serve their purpose: to be beautiful, of course!
Accurate sizing, vibrant colours, quality material and fit well on a 22mm RDA (without blocking airflow) and providing a seamless 24mm base. The drip tips are great too, well made and tight-fitting, and at a good size and height for a single-coil RDA.
There are a couple of things worth noting: Be gentle with the rings when cleaning etc, as the base is very thin and easily damaged - in which case it just becomes a friction-fit beauty ring 😊 The thin base could be a pro if you have a hybrid mech. For RDA's with non-adjustable and/or short protruding positive pins (like mine,) some beauty rings can interfere with battery connection. I have discovered (with help from reddit) that you can fix this by slipping a tiny o-ring (1.5x2x5) behind the positive pin without issue.
Lastly, I have a ⌀ 23.8mm mech, meaning the rings overhang slightly by 1mm each side, this may not be an issue for most.
I still want these in every color! (and more sizes too!)
