I can't get pass 3 -4 days and I will leak. I use the coloplast also. Don't know if it is the heat down here in the South or what. I have double checked everything and shave area well and dry before putting new bag on. I do have quite a mound that has developed. I just don't know but was tired of leakage at work and having to drive an hour home to resolve problem. When I put it on I lay down in bed and put a hot washcloth over the wafer for 10-15 minutes to get a good seal. Can't do that here at the office. lol
Amey - how's the insert working for you so far? Sounds like you might have found some success!! YEHHHHH! It sure isn't as flat as what I was used to but the extra wear time is worth it to me. What do you think?
