Advantages

- Grand ergonomic plan

- Additional programmable mouse keys which make browsing  or  working some common programs very much simpler and further proficient.
- Keyboard’s keypad is twisted faintly to have room for a additional normal hand location

- Additional button on keyboard to zoom works grand in picture altering programs

- The mouse is extraordinarily soft and has unbelievably accurate (soft) wheel scrolling

- Great worth materials is used for creation / the mouse has a great  feel and it seems  having great quality.

Disadvantages:

- The keyboard miss outs letters as we type occasionally if indicator is feeble. This is becoming further and further gradually irritated. I have newly got this to occur pretty often yet with a new pair of cells and unluckily I can’t give back this keyboard since I purchased this on 26th of April- about two months past. I may give a try anyhow.
- Clicks of Mouse are not predictable now and then. I visualize it is because of feeble wireless signal; however the mouse is just one and a half feet far from transmitter. Moreover becoming gradually aggravating. (Update: Even now very irritating. As per my view, it is a needless reason of an improvising put up of nuisance through work that sources me to be there wasteful and ill-mannered to my colleagues.)
- ‘lock’ buttons do not contain leads (on keyboard) similar to all keyboards. When we push Caps Lock button, an OSD will pop up showing that whether the Caps Lock is turned on or off. There are leads on bluetooth aerial that show which lock buttons are switched on, but this is at the back of the monitor so I cannot see it also.
- program precise settings for the mouse don’t work properly when 2 programs with dissimilar custom settings for each program are open on the similar time (ex: when firefox and photoshop are released, the mouse responds supported on photoshop’s choices so center clicking on tab to shut it really changes the mouse to particularly accurate mode)
