There is no one size fits all or better or worse ostomy appliances. You don't say what you are using...or maybe I've just missed it.

I started off using Hollister, 2-piece, flat flange. It leaked constantly. With the help of local district nurses, I ended up on Coloplast, 2-piece, deep convex flange. And over the last 2 years I've added an Eakin ring and I use Skin Tac and so on and so forth. I use Coloplast Sensura Mio with Convatec's adhesive remover, extra-thin hydrocolloid dressing, and Eakin ring, and Hollister's Extenders. And I'm thinking about switching some of that still as I search for the best arrangement. I do think that Hollister has the most complaints about quality or lack thereof, and it's my contention that Coloplast has the best track record,

In the last year and a half, I've never changed my appliance in under 7 days and often can go for 14 days. I must have the skin of a rhinoceros. (Knock on wood)
