I used to use it (better mouse) before BTT added Logitech support - but wasn't really happy with it. Every single update changed something, mostly my cursor speed in some small, but sufficiently noticeable way and I had to adjust it every time, which was super annoying.

At some point my settings kept getting lost every time my mac went to sleep, and I had to restart the app all the time. I messaged the developer, but never received any response or acknowledgement and I just dropped it. It's a pity, because I did like it for a period of time while I was initially using it.
