The discussion is about experiences and feedback on the new Coloplast SenSura Mio two-piece and one-piece ostomy systems. Here are some insights and advice shared by users:

- Wafer Comfort: The wafer is praised for being very comfortable and is highly rated by users.

- Pouch Issues: Many users experience significant pancaking due to the fixed vent/filter. The raised barrier around the vent can trap output, and the vent's location may interfere with a stoma guard. Unfortunately, there is no vent-free pouch option, and the new wafer does not fit older Coloplast pouches, which has been disappointing for some despite the comfortable materials.

- Wear Time: The wear time is reported to be poor, with some users experiencing wafer erosion and leaks within 1-2 days, sometimes leaving the skin raw. Reinforcing with adhesive spray, stick paste, and spray-on skin protectant can help extend wear time.

- Filter/Vent Performance: The Mio filter is often found to be bulky, quick to clog or saturate, and a major cause of pancaking, ballooning, and reduced capacity. However, one user with a liquid ileostomy output found the new filter reduced gas-related bathroom trips by about 40% and kept the pouch flatter. Hollister New Image filters are mentioned as more reliable.

- Pouch Handling and Construction: Users appreciate the soft quick-dry fabric, low profile, shorter length, peek-a-boo inspection window, and Velcro closure. However, they find the outlet hard to clean, dislike the clear plastic tail, and note that the bottom Velcro tab can detach. The grey fabric may tear at the mouth seam, so some users tape both sides for added strength. Snapping the pouch onto the flange can be difficult, so it's advised to test the click before applying.

- Compatibility and Options: SenSura Mio wafers are not compatible with previous Coloplast pouch lines, and all Mio pouches include the fixed vent. One user plans to cut out the internal filter layer for improved comfort. Sure Seal rings are being trialed for added leak protection.

- General Tips: Always request free samples before committing, as most manufacturers provide them. The consistency of the output (liquid vs. thick) greatly affects filter success, so diet, hydration, and electrolyte management are key factors. If issues with Mio persist, consider reverting to the standard Coloplast two-piece or exploring alternatives like Hollister New Image.
