Purchased this keyboard to use with WDTV in my living room. Just plug and play and it worked well.
Looks good and feels good in the hand with proper weight balance.

Range and reception was good and there were no missed key-presses or lag. Although, the wifi signal strength of my router in the same room got marginally affected. That is expected as the the keyboard uses 2.4 Ghz RF range similar to WiFi. But over all effect on wifi signal strength was very less and all my other wifi connected ...

Bought this keyboard to use with my HTPC and it's perfect for living room use. It's actually much smaller than the pictures indicate and fits perfectly in the palm of your hand for one handed operation. The media shortcut keys on top make it perfect for HTPC use. I would have been much happier if Flipkart had the N5902 model which has a backlit keyboard as well, but until then, this will have to do.

No F1 to F12 button on this keyboard. Works fantastic otherwise. I'm now typing even faster on this liliput than on a standard keyboard. Ha!

Very few devices like these in the market. Good to try out. Would have been better if it had a small back-light for the keyboard. Keypad is similar to cellphone usage. Has good shortcut keys and mouse buttons are well placed.

nice product with great handling but slightly smaller size... so even it can fit into your pocket. best product if you need any additional control over your system for presentation or while discussing any project..

I am using it to control my android tab connected to my TV. It works as expected, have not found any technical glitches in 2 months of usage.

Pros:
1)Compact
2)Trackball present in the same unit, else you have to use the mouse separately with a wireless mouse.
3)Light weight but yet sturdy construction (it wont break if u drop it from 4-5 ft)

Cons:
1)The keys are very tiny.. won't be able to identify them in not to well lit areas
2)Elderly people will find it difficult to use it.
3)A ba...

The product is good guys its very handy to use , But have some negatives

negatives are there are no functional keys (F1,F2,..,F12), there no seperate button for scroll only can select the scroll bar and move it up & down with the ball in the center of the keyboard like in few laptops, There is no center button like in the scroll button of mouse we use.

Its quite compact (around the size of a CD cover) yet ergonomic. The keyboard is very nice, works well with windows as well as xbmc where I am using it. The only gripe I have with it are that the trackball moves a bit when kept aside triggering the progress bar on media player. Flipkart delivered ahead of time as usual..One recommendation is to use the front facing USB port as using a rear port will severly limit range...

I have found the product useful and recommend to prospective buyers. I would have been happier if the unit would have been somewhat bigger with larger keys even at the expense of weaker portability. The keys also should have been marked more prominently as illumination level required is higher to work on it. Othewise the product is a success specially from the house of lenovo.

amazing device, very handy and usable....it has got 2 removable batteries and works wid usb wireless adapter which u hav to plug it in ur system.....it also works well with my nexus 7 via an otg cable....its amazing for delivering presentation as well, leaves a good impression...the battery backup is also good... got it for a very reasonable price....thank you flipkart
