Like the product, shelf life isn't spectacular
My wife got me this as a Christmas present a few years ago, at the time I had a tungsten ring that was extremely heavy. This was a cast improvement in many ways, I turned one in for warranty about 8 months after and grove life was great. The second one lasted a little longer, but dried up became hard and cracked just like the first one. Same thing happened after about a year for the 3rd and 4th. I reordered one that came with a BOGO last year in October and the exact same thing happened to that one after a year too, it would be a huge issue except for the fact that when they dry up the silicone shrinks and becomes difficult to remove.
The Aspire, Camo, Nomad, Tony Hawk, and Marvel ring and watchband collections are made differently with a medical-grade synthetic elastomer blend vs. the 100% medical-grade silicone of our other solid collections so they can feel and wear a bit different. But we make them like this so we can provide those cool patterns! If that doesn't work out for you, we are more than happy to get you a different style!
