Terry, I haven't. I don't have a FB account. I've reported the problems to Tandem, and to their credit they sent out their local trainer twice. She had me try other infusion sets, but there's a reason why I went with the t:90 style years ago, it's the right one for me (if it has adhesive on it.)
With Medtronics, Deltec, Animas no problems (OK, 1-2/yr, but that's reasonable) I've tried every secret under the sun with these Tandem branded Unomedical sets, but no dice.
The bottom line is there is no adhesive to speak of. And I keep getting a strong feeling from Tandem that it's not the infusion sets, but it's me. Yep, I've suddenly become stupid after 27 years of pumping.
The sets are 90% of the problem, but I've had several pump problems that contributed to 10% of my too many 450+ glucose episodes. I'm writing a review with photos that I'll post here soon to cover those issues. Non working alarms and user interface design were behind those problems.
