Tried a hand on this for a week and unable to get the addicted to this keyboard and the extra keys are a lack of design and the complete design on the keyboard is not so good as per my use.
I have used Zebronics keyboard earlier and liked it or I can say addicted but tried this new and:(.
It might be good for the gamers but I am a regular user and this does not suit at all.
Extra keys are not very useful and the design is not a fit for advanced users.
Keys are smooth as other keyboards from the zebronics.
