I got this product from egully for a good deal. Its been 6 months, Only had to change the battery once.I bought a rechargeable battery for using with this keyboard. The keyboard surface is glossy so fingerprints becomes visible.
The mouse has a on/off button, The mouse becomes heavy after putting the battery.They keyboard has all the Functional Keys. The only thing it lacks is the CAPS Lock indicator, Without typing, I cant know whether the caps is turned off or ON.
Overall, a nice product from Logitech.
