This discussion revolves around a concern with the quality of Convatec ostomy products, specifically the 413161 wafers and 401512 drainable pouches. A long-time user has noticed a change in the manufacturing process that has led to issues with the pouches splitting open. They are exploring alternatives and seeking feedback from others who might have experienced similar issues. Here are some insights and advice shared by the community:

1. **Experiences with Convatec:**
- Some users have noticed changes in the sealing method of Convatec pouches, leading to issues like thinner and noisier plastic, poorer odor control, and uneven seams.
- Similar problems were reported with Convatec urostomy bags in the past, which were resolved after switching brands temporarily.

2. **Reporting Defects:**
- When reporting defects to Convatec, send a used, leaking pouch along with the lot numbers to prompt quicker action from their quality control team.
- Convatec’s support team can provide replacements and guidance. If issues persist, request escalation.

3. **Alternative Products:**
- Hollister and Coloplast systems are being trialed by some users, with Hollister being noted for comfort.
- Specific products recommended include Hollister’s two-piece system with Wafer 11503 and Drainable Bag 18182, and Coloplast’s SenSura #15521 pouch with AllKare protective barrier wipes.
- Some users find Hollister’s plastic thinner and noisier but generally leak-free, while others prefer its flanges over Convatec’s current versions.

4. **Practical Tips:**
- For emergency situations, warming a Hollister pouch coupling with a hair dryer can help fit it onto a Convatec flange temporarily.
- It’s advisable to purchase from reputable medical suppliers to avoid counterfeit or outdated products.
- If Velcro or belt-less designs are problematic, consider using supplemental clips or belt-compatible products.
- For those sensitive to alcohol, note that Coloplast’s standard paste contains alcohol, but an alcohol-free version is available upon request, though it may take time to receive samples.

These insights aim to help those experiencing similar issues with Convatec products and provide guidance on exploring alternative options.
