Different bags from different companies work better or worse for different people, unfortunately there is quite a bit of trial and error sometimes to find the best one for you. I'd speak to your home nurse if I were you about maybe switching back to Coloplast, if they work well for you then why change to a different one? Obviously, people will have their individual preferences but sometimes the glue on one style of bag won't stick to you properly, or maybe the flange is the wrong shape for your stomach. If you had good success with Coloplast, I'd stick with them. (I'm a Coloplast user as well, the grey-colored Sensura Mio bags). Also, at first, it can be daunting trying to get the d# @ bag to stick so if you're not already, hold your hand over the bag firmly for a couple of minutes after sticking the new bag on - the warmth from your hand helps activate the adhesive. Also, with warmth, if you have access to a hairdryer, blowing warm air on the lowest setting for a few seconds onto the flange can also help. What I actually do is sit on a stool while changing and tuck it under my leg where I'm sitting, and warm the flange up that way (I don't own a hairdryer, and tbh don't really want to!). And there are plenty of ostomy YouTube channels with loads of information - Maggie from LetsTalkIBD, Amber from The Ostomy Diaries, and Eric from VeganOstomy just to name a few. Also, Hannah Witton (channel is the same name) has a whole load of stoma content. Her channel is mainly about sex education, but in amongst all that she has plenty of videos about ostomy life. Hope this all helps!
