I love my Omnipod. I had never wanted a tubed pump and avoided getting one because of that. But my endo at the time, a type 1 herself, said you should really consider a pump. I said I don't want tubes. She told me there is a tubeless pump and it's small, you won't even notice where it is and started patting all over her body trying to remember where hers was. I laughed, but now find myself doing the same thing trying to find it.
The pluses. It's waterproof, no taping off, even when I swim for hours, that also means I don't have to be without insulin when I do. It's relatively small and can be placed all sorts of different areas. I would not ever easily switch to a tubed pump.
The downsides. It either has a separate PDM or phone type of device for control, since you don't wear it you have to keep track of it. It only holds 200 units of insulin for 3 days, for most of us, that is fine, but if you use more insulin it might not be. No choice of different infusion sets since the pod is the infusion set. That usually is only pertinent if you've been wearing a pump for a while and having a problem with sites.
I have the older Omnipod, But I love my original Omnipod, it's been really easy to use, to give myself a dose whenever I want by a push of a button. You don't have to enter any information if you don't want to. You have the choice of entering BG level or carbs or both, or nothing except the dose you want to give.
The other companies have had a loop systems for longer, Omnipod just came out with a loop system. I can't comment which is better or easier to use since I don't use a loop system.
