I have had the lycosa mirror version of this keyboard, And i have only been disappointed with this. My Touchpanel goes crazy sometimes and repeatedly opens windows media player. My keys stop functioning sometimes and i have to reboot to make it work. The arrow keys get stuck sometimes while gaming especially the left key and i have to restart pc to make it work.
Whats more I also sent it to get it replaced under warranty, but the company refused to replace it stating "It works fine in our test lab"
Overall have felt like razor has cheated me entirely and will never go for any "RAZOR" product.
I've now replaced it with the logitech G110 keyboard and hell this is a major difference than lycosa.
I can change my led colors, intensity, on/off it. 12 programmable G keys with on-fly macro recording.
A nice wheel to +/- volume, mute button. Media keys. provision for headphone/mic/USB port and to put cherry on top of cake, it has its own on-board soundcard inbuilt the keyboard.
I spend almost $20 less on the Logitech G110 compared to the disappointing Lycosa mirror keyboard.
