I recently re-pierced my belly button. I decided to go with a plastic piece to see if it would help my piercing heal faster and also cause the least amount of irritation. This has been fantastic for that. It's incredibly comfortable and lightweight.

PROS:
Great if you have a nickel allergy. It's more comfortable to wear than titanium rings.
Affordable.
Comfortable and lightweight.
Not too flexible.

CONS:
After changing this once, the threading is now stripped. The ball falls off constantly.

Overall, I would repurchase. But don't expect to get a lot of use out of these (unless you plan on putting it in, and leaving it in). For the price I am okay with repurchasing these every so often. Just wish it was better quality.
