Okay, so you asked advice about the omnipod...well, I have used it for over a year now, and I absolutely LOVE it! I've never used a traditional pump, with a tube and everything, so I cannot compare it to that. But, the omnipod has DEFINITELY made a hugeeee impact (in a good way) on my life. It has made type 1 diabetes SOOO much easier to control!
So, pros: it is tubeless (without a doubt, a great thing), it is waterproof (so you can swim, shower, whatever with it...just be careful not to take the PDM, or the handheld controller, in too :-) haha). It calculates your bolus and all that good stuff...plus it has a color screen. Also, if you want, there are like these rubber covers that you can buy from the company that help to protect it if it drops or something.
Cons: the pods themselves do not stay attached to the sticky material very well. What I do, and i would recommend, is to take some kind of IV prep (which is like a big, clear, sticky thing) or something similar and use that to hold it down. (note: I am not sure about you, but I am a guy, and an active one in sports and rough-housing and stuff...and while doing those kinds of activities, the pod has a chance to be ripped off of you)...and another con would be that if you do not move the site where you inject the cannula enough and change it so it is far enough away, the injection could be painful and lead to bruising. and finally, the pod's size: they are pretty big and bulky
Well, that is my overview on the OmniPod...one more thing I would like to add: they have not put this out on the market yet, but I wanted to let you know about a new pump, similar to the OmniPod, that will be coming out soon (hopefully anyway) that is called the Solo MicroPump. It also is tubeless, and it is in fact a little slimmer than the OmniPod...just something else to look at and maybe consider (their website is http://www.solo4you.com/ )...however, since nothing other insulin pump has been released that has been tubeless, the new competition might in fact spur improvements with the tubeless insulin pump, so watch out for that.
Well, I'm sorry I wrote so much, but I hope what i said helps!
