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!

Worst update process ever. 3 weeks: buggy, annoying, opaque

I really have to express something I'm unhappy to say, because I love the Tandem pump that has been my constant companion for more than a year.

But this update process has been unacceptable. I don't think you have achieved safety by doing forecful, repetitive, redundant training which obfuscates the eight facts you MUST know amongst regulatory garble and repetition of obvious information. It is also a slow and annoying process; I've had no CGM sensor on my pump for more than a month.

Finally, the website is unreliable and the same login information (saved by my browser) will sometimes work to log in and sometimes not. Click four suddenly lets you log in.

Tandem, I love you, but developers, please have a patient run through the entire process with you in front of them. Then, you'll see how users fare and the grief, frustration and dead-end moments they experience. This is just not acceptable.

You also fail to caption your videos - it's also non-inclusive. Anyone who is deaf, uses a screen reader, or has any reasonable human need to have more than audio it interact with is up the creek.
