This discussion is about personal experiences with the Coloplast SenSura Mio Convex Flip 2-piece ostomy system compared to other brands. Here are some insights and advice shared by users:

- The SenSura Mio pouch is shorter than Hollister’s, making it easier to hide under regular shirts.
- The Velcro outlet on the SenSura Mio is more convenient and reliable than Hollister’s plastic clip, as there are no parts to lose or break.

However, there are some concerns:

- The smaller pouch volume requires more frequent emptying and poses a risk of overflow, especially after partial obstructions that suddenly release a large output.
- The pouch has detached from the barrier unexpectedly three times when brushed in tight spaces, which did not happen with Hollister’s double-arrowhead coupling.
- Although the barrier remained intact, these detachments affected confidence in the system.
- The plastic coupling ring’s rigidity is inconsistent, sometimes bending or snapping, suggesting variable manufacturing quality.

Additional observations and questions include:

- The adhesion of the SenSura Mio Convex Flip barrier is excellent, even better than Hollister’s, despite its semi-flexible rubber feel compared to Hollister’s fabric-style barrier.
- The user employs Coloplast barrier rings but is considering trying Eakin Cohesive® rings.
- Only one barrier leak occurred, which was after falling asleep following a large meal.
- The user leads an active lifestyle and is curious if activity level affects the security of the coupling.

Advice and insights from others:

1. Convatec Natura Plus 2-Piece: One user reports it never leaks or pops off, but they engage in minimal physical activity.
2. Hospital experience: Some found generic two-piece pouches unsnapped easily, causing messes, and switched to Hollister one-piece for better security.
3. Hollister One-Piece: Typically provides up to five days of wear before leaks for one user.
4. SenSura Convex One-Piece (standard, not Flip): A new user experienced leakage within one day, suggesting that fit or application technique may be critical.
5. Ballooning issue: Significant gas build-up can enlarge any pouch. Although bags have held so far, it highlights the need for vents or frequent venting to avoid potential rupture.
6. Sampling different brands and flange styles (Coloplast, Hollister, Convatec) and using barrier rings (Coloplast rings, Eakin Cohesive® rings) can help identify the most secure and comfortable setup for individual activity levels.
