In keyboard I think we can only trust logitech brand, as I am using the same model for the last 6 months I feel that my investment are in good place .
I used more than 10 brands but not satisfied as all the keyboard are stoped functioning
this model are very much confortable to use as the keyboard are soft and freely typing .
Always go for logitech brand if the budget are around 1000 Rs.
Customer are also very perfossional as I called them to know how to register the product online, they explained all the process and also advised that if there is any problem than they are providing home services as well.
