The K70 uses Cherry MX Red key switches, which deliver a smooth, linear key response with a wide actuation zone. They have the responsiveness you need for perfectly executing double and triple taps, and there’s no audible click or tactile “bump.”
Each key can be individually coloured, allowing a wide range of profiles to be set up. This enables the highlighting of important key groups in games, for instance (some games will have preset profiles for this).
Some might have bought it when there wasn't many other of the options available today from Logitech but it might be worth looking at the cheaper models unless you are looking for some very specific look or characteristics.
With a retail price of $96.86, this keyboard is considerably more affordable than most ergonomic keyboards on the market. It doesn’t have the same caliber as more premium keyboards, but it’s a top option for those on a budget who are looking for a good ergonomic option.
There is an on off switch on the keyboard that allows the user to turn off the backlight illumination of the keyboard. This is a lot easier than using software on the PC as it is more accessible, especially if the screen is off.
