Logitech MX Vertical Advanced Ergonomic Mouse

I have used the various M500 series mice and ended up with the Signature M650L Logi mouse to work with my MX Mechanical keyboard.. The MX vertical seemed like the ultimate upgrade as it supported up to three devices and (as is the keyboard) is charged via a USB Type C port rather than having replaceable batteries. But, it uses the older USB Unifying Receiver rather than the USB Bolt. I have one of each receiver plugged into the computer to support mouse and keyboard. I find that the MX Vertical Mouse is far easier and more comfortable to use that any of the other Logitech mice I have used, including the rollerball. I realise I was twisting my hand to use side buttons and mouse clicks were made more with the side of the fingers than the 'fingerprint' area. The vertical mouse places all the controls, including the side buttons, naturally under the fingers and thumb with the hand resting naturally on the desk. It is right-handed, only. I'm not going back. It loses no stars for the use of the old unifying USB receiver. I notice that I have to twist my hands to type. MX Mechanical Vertical keyboard, anyone? And a very fat laptop bag?
