Insulin pump choices?

I've been a diagnosed type 1 for 30+ years. I'm 40 years old and have been using a pump since age 12. Started with disetronic, then minimed, then roche, back to medtronic, and now using tandem. CGM tech is absolutely amazing but only if it's through dexcom. I had to switch to tandem due to the absolute crap that is the guardian cgm system. If you sweat the guardian sensor fails, if you look at it wrong the guardian sensor fails. Utter garbage.

The tandem pump is junk that is marketed towards younger diabetics. The pump is not resilient and has oddball software issues that leave the user unable to trust it. Yet, the medtronic pump refuses to work with the better dexcom cgm system.

What can be done if you want the tougher, water resistant medtronic pump but want to be able to use the dexcom cgm?
