Hi Alistair,
I have had a permanent ileostomy since December 16, 2011, and I got my Stealth Belt within about 6 months, I think. Honestly, it's the best investment I've made. Unfortunately, I'm not so active post-op. I had a lot that happened to me during and just after surgery that has made me more sick than I was originally, which caused me to have the surgery to begin with. But, I do have nearly daily doctor's appointments, or at least I'm traveling to and from the hospital up to 3-4 days a week, and I'm there for 1-2 appointments a day. Having the Stealth Belt really helps me not have to worry so much about my bag at all. (Sometimes though, it lets me totally forget about it to the point that I forget to check it because it's not hanging down and getting heavy when it's too full, which reminds me to empty it!) I even recently bought myself a second belt because the first one I bought was for the looks. The second one I got in plain white so that I can wear it under certain clothes and not be seen. I've been to the beach with mine (I live in California, in the OC). I've been in swimming pools with it, was a bit scared at first, but it was also right after I had my surgery. I was more worried about my bag hanging in there than anything. I've learned in the last 4 years now that I don't really have to worry about that at all, and the Stealth Belt just makes it that much easier, for literally everything. For me, the most important thing is that they are custom made, so they fit perfectly. I happened to gain weight slowly after my surgery, but that's from the Crohn's. The belt was made to fit perfectly at the tightest point. So when I gained weight, I just moved the belt over (Velcro, and triple-layered so there's no way for it to "accidentally" come off). So the belt fits me whether I gain weight or when I lose, which is great, I don't have to buy new ones as often as I am having to buy new clothes!
One last thing, and maybe this is more so from a woman's perspective, but I had always had a flat stomach until my surgery, and some of the meds they put me on, and the weight I gained after maybe a combo of all the above, I don't know, but it makes me extremely self-conscious about how I look now vs how I looked pre-op, but the way the SB is made, and the way it fits, it actually holds me in, and I can wear my nicer clothes without being embarrassed. I have pictures of me where you can see my bag under my clothes (or at least I can, but I'm very aware of it) and I also have pictures where I'm wearing my SB and you can't even tell I have a bag at all. It even helped with me being so aware of having the bag, when I wore the belt, people that saw me on a regular basis and knew I had the surgery, eventually just completely forgot I even had the bag! Keeps it out of sight, out of mind! Totally helps my self-confidence as a woman, even though I am not able to go back to work in my profession. I can still dress the part when I have to leave the house.
I hope this helps a little bit, and sorry for going on and on. I honestly can't say enough about SB. I'd get another one if I could, since I have changed bags recently, and it is important to have the correct size belt for the bag style that you wear. I change bags often enough that I need several belts! Oh, and if you haven't looked around their site, or followed them for a bit, they have giveaways, and they offer deals on eBay as well. You can follow them on Facebook, Twitter, email, etc. I got my second belt on eBay, as they have belts that maybe (I am only assuming here) were made for someone specific, that probably didn't purchase it for whatever reason, or returned it. So since it's a custom-made item, it was made to fit that person, and their bag type, but if you keep a watch on them, they just might end up having one your size, but beware of the flange size, that makes all the difference too!
