The Oura Coil V2 was recently released with some improvements to make it easier to install and use. The top metal ring now slides into place and is held on by the silicone band around the top of your atomizer! This makes the entire coil much easier to install and remove from your device without accidentally removing the top ring instead. Additionally, further structural support was added to the base of the plate underneath the coil to ensure that the coil doesn't shift of move around when physically pulled on or moved.
