I ordered the ring for my wife. Of course, too big ;-) After a call, the matter was clarified with the supplier. I sent back the ring and promptly got a new delivery in the right size. At no additional cost for me (except the postage for the return). In short, nice competent contact and problem-free settlement.
For the product itself: The Noosa chunks fit perfectly into the opening provided in the ring. Fits wobbles and has air it says so beautiful in the vernacular. So, everything was perfect. Whether that will be in the long run so I can not say, but the ring does make a robust durable impression ....
