I’ve been using it since it came out. Warm up period is 25 minutes and is the size of a couple quarters stacked together.
The whole thing is disposable, so no need to transfer over your transmitter between sensor changes. Definitely (not the greatest thing for the environment, but I won’t deny how much I love the low profile that grants it). The injector is much smaller and the application process much smoother.
It’s a huge improvement over the G6, but is still unsupported for closed loop systems like the Omnipod 5. You can use it with the Omnipod Dash or another supported pump using Loop to achieve a closed loop system if you’re into that.
