1- no, not at all...its gone off only when necessary, none other times...and the time it was disconnected, it alerted me right away too..plus the alarms directly say whats wrong, they dont have codes and all
2-it does look huge, and at first i thought so, but once i got it, i didnt...mine is rarely visible...cant be seen under any t-shirts, sweatshirts...jean skirts...dresses...then, with jeans, it loooks like u have something in ur pocket...all other shirts vary, but still, its pretty hidden...it just got some taken used too..but its never been much of an issue (althought that was originally my biggest concern!)
i roll a ton at night, and although i am aware its there, its not like its uncomfortable, although i thought it might be...i sometimes just put a pillow under it if its in a reallly bad spot (like my back)..and the issue is solved...but i think personally its still better than dealing with tubing during the night
3-nope, i havent had those issues...it has come out before...but it was from a TON of water pressure (attempting to barefoot)...and it was in a bad spot on my leg...also, it really stays on well..the adhesive is stong, and they sell wipes to make it stick even better...usually my problem is getting it off...lol...i think u'd be surprised at how well it stays on...i change a lot, and never have gotten it snagged...
i wear it alllll over...arms, thighs, back, stomach, even butt...and as long as ur doing relatively common activities (sports, swimming, showering, changing), u'lll be fine...at first i was very protective of my site, but now im not, as there is no need to be
its not as bulky as it looks, really...u can order a free one from omnipod
hope this helps, and ask if u have ?'s
