I love my tslim but...

This upgrade process has been tedious and overbearing:
1. Waited over a month for the prescription phase because tandem thought they sent a request to the doctor when it turns out there was never a confirmation it was sent and they just stood by until I called.
2. The training course does a great job at being thorough, however for those of us with more than a neanderthal understanding of technology will be banging our heads against the keyboard while you must wait for the (slow paced) recorded instructions to finish before continuing.

I understand that the amount of update requests has been a burden on the company infastructure, but I think more benefit of the doubt could be given on the customer's part to help cut the fat off of this process.

With all that (bluntly)said, I am more thankful than anything to be a part of this ecosystem and enjoy the cutting edge tech tandem provides (relative to the medical industry...) and continue to use tandem pumps for the future to come.

don’t let the spinning wheel deter you

This review is for the Control IQ update. I am a luddite and thought the spinning wheel after I clicked the update button on the app store page meant that it hadn’t finished downloading (and was buggy). What I realized after a few tries is that it doesn’t let you know when the process is complete; the wheel just keeps spinning. Once I looked in applications on my computer the updater app was indeed there. From that point the pump update process was very easy. Hope this helps!

Very pleased

Tandem is an exceptional company. I have been blown away with my new Tandem pump, and with this amazing Control IQ technology. My update process was smooth and easy. The required training before you can update is likely required as part of the regulatory process. RIght now, I have a Dexcom G6 CGMS working perfectly with my Tandem pump. I have received amazing help from Tandem reps and from clinical nurses who work with Tandem to ensure that I had substantial and effective help and guidance. So, for me, my experience has been very positive. Best wishes to you all.
