Pumps

I think I am ready to take on a pump. I’ve been really looking at the OmniPod. It seems like people either love or hate it. Also, I’ve read a few things that they will be working with DexCom 7+, but I’m not sure if that is true. The other pump I’m thinking about is the Ping. I am a first grade teacher, and a little worried about the kiddos pulling on the tubing. Anyone have any good/bad experiences with these?
