I've been using the OmniPod 5 for about three months now. I chose it over other pump options because it's a pharmacy benefit allowing me to switch to something else later if I didn't like it (or something better came along - like the Twiist?). Going with the Medtronic or Tandem pump go against my "durable medical device" insurance benefit and is a four-year commitment. Something you might want to consider as well.
I've had no problems with the pump. I thought it would be difficult to sleep with but it turned out to be a non-issue. Nor have I had any problems with bumping it, etc. In fact, I have more problems with the Dexcom G7 and its reliability than I ever have with the OmniPod. It's only an issue "in public" at say "pool parties" as I might be a bit vain and don't want everyone to see it. But, at 60yr old, such situations are increasingly rare :). The algorithm used by the pump does a pretty good job keeping in range most of the time. And that's impressive given that my pancreas still makes an occasional showing but to throw some randomness in the mix.
Maybe one minor issue is that it requires 85 units minimum and I'm not using that much insulin (yet) over its three day span. So, there's some waste. If that's true for you as well, make sure your insulin prescription is written for the amount of insulin the _pump_ will require and not what _you_ require.
Let me know if there's any other questions I might be able to answer.
