Omron's Romer G's are exclusive to Logitech if I recall correctly, they have been in just about every keyboard the company has put out recently.
The G410, G413 G610, G613 Wireless, G810, G910, K840, The Pro
They are all gaming focused boards in terms of their design and marketing, with the exception of the K840 which means their features, aesthetics and functionality is focused towards gamers and you either love it or hate it.
I appreciate the effort that Logitech and Omron took to design and create their own switches in-house instead of attempting a remake the Cherry MX switch design though, kudos to them.
