You should not use this if you have Type-1 diabetes. It's (supposedly) not cleared to the same FDA standards, and if you tell the app you're diabetic, it locks you out from using this. I'm under the impression the Stelo (OTC version) is the same as the G7 (prescription version) with a different logo and box. I think the only practical difference is that this version has a longer lifespan (15 vs <10 days), and that it's not configured to actually alarm when it detects something dangerous. I'm not sure if any science showed the last 5 days have reduced accuracy, but I wouldn't risk my health on it if there were alternatives available.
If you have T1d, you've been able to get the prescription-variant of this product for years with insurance, so there really is no reason to get this unless you're un-insured.
