Review on Logitech Master Advanced Wireless Mouse Computer Accessories & Peripherals for Keyboards, Mice & Accessories by Frank Chinchilla

There are several reasons to buy this mouse. The setup is basically as good as it gets. If that's your reason for buying this mouse, you won't be disappointed. If you buy this mouse for the device switching function, keep looking. I mean sure you can use it to switch devices with just a push of a button, but some NULLER thought it would be nice to put the toggle button DOWN and then make it the only function you can't remap. and it gets worse. If you have an MX Keys keyboard, you can't sync them, which means you have to press two keys, even if they're connected to the computer using the same key. If it was the 1st gen version I would understand. How to jump to multiple generations without moving the button so the button can be remapped or changed using the keyboard? Seriously, that's the only thing I don't like about this mouse. If this problem were solved it would be a real five star product.
