I've had the same problems Spiker, although with me, it feels like it goes in fine. Changed on Fri and used a 30, stang a little bit, but not a lot, yesterday morning a small dose of 2.50 to cover carbs, stang like hell and every time I bent forward it stang, went of when I went out to my parents, dosed for tea, which was a larger dose, but that didn't hurt?? But the first one I used I pulled apart lol. But the second one I used went in fine but when I rolled over in bed, it occluded only once, re primed and it was fine. But after yesterday's performance I've gone back to using inset ii as well.
