I've got several of the Accu Chek cases, 1 of the skins and verious kinds of phone or compact camera cases..
I tend to use the clear clip case 98%, 1% of the time (mainly when I doing agelity with the dogs) and 1% of the time a compact camer case that I can sercurly clip to my blet hoop on my jeans, if I'm out on rough terrian with the dogs!
But I would suggest looking at some of the different phone case on the market, just ensure that they don't have a magnetic closure give you more choice..
