Hi Vollovr, It is disheartening but not surprising to hear this is happening, with the way things are these days. Products are not made to last anymore, in fact the opposite is true. I don't know when you, and others, started to experience this change, but just for the record, when I got my colostomy just over two years ago, I started using Coloplast products and I found I was getting pretty good wear time, 4-5 days, but honestly I wasn't testing it beyond that point, too nervous about leaks. Then I got an ileostomy just over one year ago, and the wear time I was getting with the Coloplast was terrible, 2 days tops. I switched to Hollister and thing improved a lot, but I still had to try a few different appliances before I found one that really works for me. It's the one piece, #8958 is the product code, and I only need to change every 6 days, in fact I've pushed it to once a week a couple of times and I was fine. I do warm the flange with my hair dryer before appyling and hold it firmly in place for a good 90 seconds. Maybe worth a try. There are so many different products out there now, and as much as it's a pain in the #%! to have to look for a new system after so long, it might just be worth it. Good luck!
p.s. I would also be complaining to the company. If nobody does, nothing will change.
