I've used the Hollister #8805 barrier ring since my ileostomy in 2018 without any problems whatsoever. However, within the past three to four months, they have been completely different in color, texture, appearance, and most importantly, reliability! I've reached out to Hollister and inquired if something has changed, but I have not received any answers. They just ask me question after question. i.e.: who is the shipper, the supplier, the dates ordered, the order numbers, the lot numbers, the expiration dates, when ordered, when shipped, am I using them correctly, etc.! I have answered all of their questions and then some. I thought they were truly interested in my inquiry. - Then ... crickets. I haven't heard a peep back.
So, after many horrid leaks and barrier failures, I took matters into my own hands, (as many of us ostomates often have to do), and figured stuff out on my own. Here is what I found: (I do not know if it will be helpful to anyone, but just in case it is...) :)
Convatec has a -try Eakin Cohesive barrier ring request a free trial- program. They have different types to choose from. If the type you chose to try did not work well, or if you feel you need to try a different one, they will send you another of your choosing. I stumbled upon this while bawling my eyes out scrolling the internet looking for a barrier ring that is reliable. I found it through them.
Again, I don't know if this will help anyone - but just in case it might, I am posting my experience. Take good care everyone!
