Struggling with Clickable Colostomy Pouches - Need Advice!

I am 3 1/2 weeks into having a colostomy. Everything was going fine with the Hollister pouches 70mm. Large pouch closed end. Then I just changed to what I thought would be a good choice the sen sura clickable pouches. I was able to change the Hollister pouches myself. Now I'm having trouble getting the clickable pouches on even with my husbands help! Has anyone had this problem . . . or what are we doing wrong? HELP I'm hoping to exchange them<

take a q-tip and put 1 drop of dishwash liquid on it, rub the on the two mating surfaces, it will act as a lubricant and help things snap together easier. try this at home first as it might also let the pouch separate easier before the soap dries.

I personally had a difficult time with the Coloplast pouches - not just the click mechanism, but also the heavy weight of the flange.  I've been using Hollister now for 5 years - I love the light weight of the whole system the cloth feel and the beige color.  But for some people Hollister doesn't provide enough security.  If that is the case for you I'd recommend Convatec - I have found it to be the most secure - in fact SO secure I couldn't get the flange adhesive off when it was time to change (and I didn't like the white tape).  Best of luck finding your right system.  :)
