Love the concept - add Bluetooth to Libre. App is better than LibreLink, hardware is functional, but the strap is terrible. Why a strap you say (since they don’t tell you this in their advertising)? Well the hardware don’t snuggly fit the Libre, it loosely fits over. Hence Ambrosia provide a rubbery cover and a strap, both of which are a disaster and make it frustrating to the point of throw away, if not for the cost. Abbott should buy Ambrosia, and/or integrate Bluetooth into the Libre, switch to the Ambrosia app, and skip this (please be temporary) workaround/hack.
