This is a very economical wireless solution for those looking to buy a good brand combo.U can get cheaper solutions from iball and other lesser known brands.

I have been using it from 4 months. It comes with duracell batteries and I suggest u to buy only alkaline batteries for these as they will give a very long life.

I bought it for 1350rs in hyd .Setting it up is very easy also.

Pros:

1) Lightweight

2) range is good

3) shortcut keys on keyboard are very useful

4) Very good battery life , havent changed till now

5) Comes with duracell batteries

6) low battery indicator

7) The keyboard has a spill resistant dign which means when u spill something on it there is a small hole at the bottom so u can drain it off.

Cons:

1) mouse is heavy, but keyboard is light

2) Unlike logitech which gives a small pendrive like reciever, microsoft gives a big one

If u want to know where I bought it , u can mail me
