The renderings of the image on this ring are unrealistic. You will not see all the details and individual stars as clearly as the marketing shows. In reality, the image is printed in lines that you notice when looking very close.
However, I was expecting this. While disappointing that no actual photograph of the ring is on the Groove website to set realistic expectations (makes me hesitant to buy future Groove rings that don't have user-submitted photos), nobody should ever expect a highly detailed image when printed that small. From a normal distance, the ring looks good! I am happy enough to wear it, show it off, and not request a refund. Just know that you won't be able to gaze closely at the wonders of space.
You should also know that the ring is not made from the same type of silicon you may be used to with other rings, but this does not affect how comfortable it is to wear.
My one true concern in that the printed-on image will wear off quicker than I'd hope, but one can only wait to see.
