This topic is about a review of free barrier ring samples from Trio Ostomy Care USA. The person who tried them shared their experience and some helpful tips for others who might be interested. Here’s what they had to say:

- The barrier rings are very flexible at room temperature, so there's no need to warm them up before use.
- Instead of having a paper backing, the ring is attached to a plastic case. You’ll need to peel it off slowly.
- The ring can be stretched to fit around the stoma and then slightly contracts, providing a snug and "perfect" seal.
- The performance of these rings is considered better than other barrier rings previously bought on Amazon.
- The reviewer suggests that others should try requesting the free samples, mentioning that trying something free is always a good idea.

Additionally, some forum members are planning to visit the Trio Ostomy Care USA website to request their own free samples, indicating that the offer is still available and easy to obtain.
