Topic Explanation:
The discussion in the forum revolves around personal experiences and preferences between two ostomy supply brands, Coloplast and Hollister. The original poster is seeking insights from others who have used these brands, as they have had mixed results with Coloplast and are being introduced to Hollister by a nurse.

Advice and Insights:
1. Personal Preference and Comfort:
- Ostomy products are highly personal and what works best can vary significantly from one person to another. Comfort, skin reactions, and the effectiveness of the seal are crucial factors.
- Some users find Hollister products to be more reliable and comfortable, reporting fewer leaks and failures.
- Others prefer Coloplast for its Velcro closure system, although some have issues with allergies to the tape borders.

2. Trial and Error:
- It is recommended to try samples from different brands to determine which works best for your specific needs. Contacting companies directly can result in receiving free samples to test.
- Experimenting with different types of products (e.g., two-piece vs. one-piece systems, different flange types) within the same brand can also be beneficial.

3. Skin Sensitivity and Reactions:
- Be aware of potential allergic reactions to materials used in ostomy products. Ingredients like adhesives and dyes can cause skin irritation, particularly in individuals with sensitive skin or specific conditions like urticaria.
- If experiencing skin issues, consulting with a Wound, Ostomy, and Continence (WOC) nurse can provide tailored advice and solutions, such as using silicone tapes if allergic to standard adhesives.

4. Support and Resources:
- Utilize resources offered by ostomy product manufacturers, including customer support and access to ostomy nurses. Some companies provide free advice and sample products to help find the most suitable option.
- Contact numbers for free samples or advice from Convatec were provided for users in the US, UK, and Canada.

By gathering a variety of experiences and testing different products, individuals can find the ostomy supplies that offer the best fit, comfort, and reliability for their personal situation.
