The keyboard itself is amazing and Logitech did a great job with this one. -Firmware updates and iCUE updates need to send promotes to the desktop! So I decided to take the plunge and buy them since they were on sale for $109. An online vendor should add much more scrutiny to a pair prior to sending them out. I have a small head, so it would be better if they could be adjusted. Just to give frame of reference. A significant improvement has been made on platter density (now with rubber dampening on bottom of platter), arm leveler is now slightly recessed for better angular approach to the platter, smaller platter profile thickness also improves arm angle of address to the vinyl, dust cover has a thinner profile because of the slight recesses to the above mentioned and greatly improved motor torque. I saw that the 2020 pair I bought was a revised version of the 2018 pair, so I got my hopes up. 9 x 0. The caller can hear me loud and clear.
