As a long-time trackball user, it took me a day or two to adjust to the ergonomics of this mouse, but since I did I have been enjoying using it. I have the receiver plugged into my desktop and have connected to my laptop with Bluetooth. The mouse works perfectly on both systems and the button with indicator lights for switching between them works well.

The only problem I have is that the back button on the side is quite far back and I would have found the side control cluster more ergonomic if it was positioned slightly more forward.

First, the cons. I do wish it had USB-C charging, instead of the current m-USB. The mouse does feel too slippery on my mousepad. However, I'm sure this will change with time, wearing in and all that. The DPI options are not too flexible, such that it sometimes feels that I'm either too far above or below my sweet spot.

Now, the pros. The ergonomics, in my humble opinion, are excellent. The side scrolling wheel is a nice addition. It certainly looks good too, without the overstated "gamer" look on so many comparable mouses.
