Good news is I was able to replace this mouse with the Logitech M720 Triathlon.
I work with 2 laptops and 3 screens. Bought this mouse and the K850 keyboard to quickly switch between laptops/screens. Ran into some design issues with this mouse:
1. The button to switch laptops is on the bottom of the mouse so you can't quickly switch on the fly. You have to turn the mouse over and press the button with other hand every time you want to swap devices. Other Logitech Flow mice such as the M720 Triathlon have the button on the top within easy reach.
2. This is a big mouse (palm design) and pretty heavy. I prefer a smaller mouse that's also better for travel. The M720 Triathlon is smaller and lighter.
3. Laser didn't respond well to my hard mouse pad
4. The gesture button is nearly impossible to press. It was so hard that I didn't even know it was there. Trying to program commands with this button was futile.
What I liked about this mouse was the power supply. You can recharge without having to replace AA batteries. Wish more mice were like this.
TIP: If you're using a Logitech Flow mouse, install the Flow software first and then connect the mouse via Bluetooth. I did it the other way around and had to reconnect my mouse.
