Those are cool. This one is slightly different (different finish and tread pattern) that ones I'm used to seeing. I'm glad to see another company entering the market.
On the video in the link they showed adding "nail trimmer strips" to the wheel which is an intriguing idea but I think this is not advisable for chinchillas. Their nails do not tend to overgrow and they do tend towards issues with dry skin and cracking on their feet. Otherwise I think the flying saucer design puts chinchillas in the best orthopedic posture although they do take extra floor space.
In practice the wheel itself actually is silent but the pattering of feet on it is far from it! At least that is my experience with a regular vertical wheel that has ball bearings.
