Tandem infusion sets are horrible
I find the Tandem T-slim X2 pump itself to be very good despite the cumbersome steps to refilling it with insulin, but a good pump is useless if there aren't good infusion sets to go with it. I have 26 years of experience with using an insulin pump with infusion sets. I have never been more frustrated with it than I have been for the past year since switching to Tandem. I have tried nearly every infusion set they have and none of them work as well as the Medtronic infusion sets. I understand the infusion sets are primarily made by the same company, but either it is a poorer design or poorer quality materials. I'm lucky if I get more than 24 hours of good delivery from a Tandem infusion set before it starts leaking, and that is if I divide large insulin boluses into a couple of smaller boluses because anything more than about 5 units at one time is more likely to leak. (I got the idea of dividing boluses from a social media group where other Tandem users were having the same issue.) This also means having to take insulin at least a half hour before eating so I have time to do more than one bolus and it has time to absorb. If my insurance company would allow me to, I'd go back to Medtronic immediately just for the superior infusion sets that helped me maintain more stable blood sugar control. Both Tandem and Medtronic have pros and cons, but again, a pump is useless without effective infusion sets and Medtronic's were much better. If you take very little insulin such as no more than about 4 or 5 units of bolus at a time, are on a low steady basal rate, and can afford to change the infusion set every 48 hours, you'll probably do fine with Tandem T-slim. Otherwise, the infusion sets will likely be an issue.
