This topic is about someone who is currently using a Coloplast one-piece pouching system but is experiencing issues with odor after just one day. They are thinking about switching to Coloplast two-piece pouches, specifically models 11474 and 10512, and are seeking advice on how these might help with odor control and ease of use. Here are some helpful insights and advice from others:

1. Two-piece systems from brands like Coloplast, ConvaTec, and Hollister are often recommended:
- You can keep the flange or baseplate on and just change the pouch as needed. This makes cutting and fitting easier and can help reduce skin irritation.
- Many users find they can leave the flange on for over 10 days, changing the pouch every 5 days or sooner if they notice any odors.

2. To help reduce odor:
- Rinse the pouch thoroughly after each time you empty it. Regular irrigation can further help minimize any smells.
- Keep in mind that built-in charcoal filters might not be very effective, so regular pouch changes are still important.

3. If you're considering trying new products:
- Contact customer service at Coloplast, ConvaTec, and Hollister to request free samples of their two-piece flanges and pouches, including the Coloplast 11474 and 10512 models. This can help you find the best fit before making a purchase.

4. If you decide to switch systems:
- Consider donating any unused pouches to community members who are uninsured or in need.
