This topic is about someone experiencing issues with leaks while using the Coloplast SenSura Mio Convex Flip pouch. Despite finding the pouch comfortable, they have encountered leaks each time they used it. They also have trouble attaching an Osto EZ Vent to manage ballooning, as it leaves residue on the pouch fabric. Here are some insights and advice shared by others:

1. Some users have had success with other Coloplast convex products, like the SenSura Mio Convex Light or the regular Mio 2-piece, which might suggest that the issue is specific to the Convex Flip or individual fit.

2. To improve adhesive performance in cold conditions, try warming the wafer before application. You can do this by placing the wafer, with the release liner still on, inside a wet hand towel and heating it in a microwave for about one minute.

3. Consider creating a double seal for better security:
- Apply ostomy paste or putty around the cut opening of the wafer.
- Use a moldable ring around the stoma on the skin.
- After positioning the wafer, press the area around the stoma with a short piece of PVC pipe fitting that fits inside the wafer’s inner ring. This helps to "smash" the paste and ring together, forcing paste into any gaps and enhancing the seal.
- Smooth the outer wafer edges with your hand to ensure full contact.

4. Cold weather can affect wafer adhesion, so warming the wafer and using extra sealing products can help compensate for this.
