I wore one, but had some trouble with the glue, by day 8 or so it seemed like it was on the verge of falling off, so I added some medical tape which annoyed my skin.
I suspect these devices will never go beyond 14 days at a time simply because of the glue issue. My skin was also pretty irritated once I removed the device, with some blood where the device sat.
If you chose to wear one, especially in the summer, work very hard at removing all oils from your skin before you apply it. Soap and water (preferably real soap, not SLS), and then alcohol to get everything.
I discovered that my wake/sleep cycle affected my blood sugar as much as, or even more than, what I ate.
I had the same issue with the Stelo tape. There's plenty of aftermarket tapes on amazon that fit the device profiles perfectly.
I wanted a Gantt chart and while I did achieve what I wanted it wasn't without having to delve into the their source and putting log statements everywhere.
I happen to be using ant design and I've had the same issues there.
Its a bit all over the place and the translations are not great, but i will stick with it.
I also made the mistake of using Ant Design Pro Forms since I wanted to use the StepForm Wizard component. All of the tsdocs are in Chinese and it's barely documented for more than their example use cases :'}
