I have had the 100% exact OPPOSITE of this in terms of my experience with the Omnipod and Insulet. From day one of getting my sample pod, they have been prompt, helpful, informative, and generally on the ball with everything.
As for pods failing constantly - I have had not had a single pod fail me without reason. I do get occlusions every so often, but it's usually an issue of where I placed it. Insulet has been very firm about their willingness to replace any pump that fails, at least to me. I always try to carry around one extra pump and insulin too - just in case something happens. They have always adhered to me very well also, though I know some people say they have trouble with it. They also always ship my new pods out to me early, which is nice.
And no, you don't lose all your insulin if you, for whatever reason, lose/need to change a pod early. Just withdraw the insulin back out. I know you're not *supposed* to...but I haven't ever seen a problem doing that either and I know many other people do this as well.
And I LOVE the meter it comes with. The sample size needed is one of the smallest on the market. Again, I've never had an issue with the meter readings being off. AND the one time my meter broke (I dropped it one too many times I think, lol) they sent me a new one fast and speedy with no questions asked. The only downside to using their meter is that the Freestyle strips are more expensive. Having your pdm for your pump and your meter all in one is convenient.
I like that it's waterproof and doesn't protrude under clothing, even for thinner people. I like that I don't have to worry about somehow getting caught on tubing either in my sleep or day-to-day activities. I'm not trying to sell the Omnipod as an end-all-be-all, but I honestly have had nothing but positive experiences with both the product and the company. I know for many that the Omnipod is too expensive, so check out what your coverage is with your insurance too.
Each pump out there has its own pro's and con's and you should definitely look into each and decide what will fit your needs best. Wish you all the best and hope that you have a good experience, whichever pump you go with!
