So there's an app called Bluetooth Battery Monitor (https://www.bluetoothgoodies.com/) for Windows which seemingly does exactly as it says in the title - shows the remaining battery for BT devices. It's seems like a very nice thing to have, since Windows doesn't have the native support for it (Windows 10 1809 "has" it, but only for very specific devices, as explained in the website).
Anyone else has tried this piece of software? Is it any good? Also how's the trial? Maybe there's a way to extend it? I would buy the software, but firstly I'm thinking of trying it out first, but 14 days seems like it isn't much.
