Positive:
- Sound control with roulette, mute and music control keyboard: it is a strong point.
- Adjustable backlighting, nice to tune the keyboard to the mouse and other desktop items.
- Practice 2 USB ports for connecting a USB drive on the fly or dongle.
- Separate power supply: some see it as a failure, but I have a power supply that is right and I am glad that this keyboard is feeding itself without pulling on the PC.
Negative:
- Fingerprints and dust: this keyboard gets dirty quickly (the new range gets a special varnish but it is expensive layer).
- LCD untapped: the small screen does its job but it is badly exploited (no or little apps and bug a few times from sleep). On G15 LCD SirReal I used but I can not find the free equivalent of G19 and impossible to operate LCD Host.
