I currently have an omipod insulin pump but am finding that i am limited to where i wear it. I am due an upgrade and have been offered the medtronic 780g, tandem tslim or stick with omnipod. I would want to go on closed loop system with whatever one i choose although that appears to be on hold at the moment in my area. Any advise/opinions on any of these pumps? Think i may take bad with tethered.
