This discussion is about comparing Convatec and Hollister moldable wafers, which are products used by people with ostomies to secure their stoma bags. The original poster is happy with Convatec wafers but has some issues with them and is curious about trying Hollister wafers. Here are some shared experiences and tips from others:

- Convatec moldable wafer experiences:
- Some users have experienced leaks in public or "poop tracking" under the wafer, particularly with the one-piece moldable system.
- A couple of people found that cutting a standard wafer themselves was more reliable, although it takes more time. Preparing several cut wafers in advance can make things easier.

- Hollister moldable wafer experiences:
- A caregiver managing a challenging convex stoma found success with Hollister's two-piece moldable wafers, achieving 3-4 days without leaks. They used a combination of:
- Adapt adhesive spray on both the skin and wafer
- Adapt barrier ring around the stoma
- An additional oval convex Adapt barrier ring on the back of the wafer
- Three Brava ½-moon barrier strips over the wafer edge
- This layered approach has reportedly prevented failures.

- Comparing one-piece vs. two-piece systems:
- Users who had leaks with Convatec's one-piece system switched to two-piece systems (either Convatec or Hollister) and found benefits such as:
- Easier gas release without removing the entire appliance
- Longer wear time, with one user reporting 6 days per flange and pouch.

- Alternative products & accessories:
- One user initially had an 8-day wear time with a Coloplast one-piece pouch, though durability decreased over time.
- Coloplast Brava Y-shape barrier strips, as well as circular versions, can provide extra security at the edges. Samples are available upon request.
- Hollister, Convatec, and Coloplast often provide 2-3 free samples of wafers, pouches, and barrier strips if you ask.
- "Slims" are low-profile wafers that fit snugly and discreetly on the abdomen, though the brand wasn't specified.

- Sampling advice:
- It's a good idea to contact the customer service of each manufacturer or visit their websites to request:
- One-piece and two-piece moldable systems
- Pre-cut and cut-to-fit options
- Barrier rings, strips (like Coloplast Brava Y-shape), and adhesive sprays
- Getting multiple samples (usually three per product from Coloplast, with similar quantities from Hollister and Convatec) allows for thorough testing in real-life situations before making a purchase.

- General tips:
- For stomas with irregular or changing shapes, cutting wafers yourself often provides the best seal.
- Keep a pre-cut emergency wafer in your purse or travel kit for convenience.
- Local ostomy nurses can be a great resource for trying out products and learning fitting techniques.
