Excellent product in terms of build, quality. Good key flex. However, buy this only if you are looking for portability. Because it is a non standard sized keyboard please do not expect good typing speed. I still prefer 11-inch keyboard as this is at par with any laptop keyboard and has the same distance between the keys which is good for fast typing. So I got this replaced with another iBall BT Keyboard which was also having excellent quality at this price line. iBall products are very reliable.

Update: 4 months on and the keyboard is as useless as ever. I have given up trying to make it work and have ordered a new keyboard - a USB keyboard this time. I am done experimenting with these new technologies. They are not reliable as yet - at least not low cost ones. If you want to risk your money with such hyped up products at least have a fallback device which you can use in case the product fails to function as per the manufacturer's claims about it's "manufactured" reliability - so that your work doesn't take a hit.AND they even increased it's price - I got it for 1500 bucks! Another over-priced but useless "high-tech" gadget. Ruben Goldberg machines are better compared to these worthless specimens of substandard electronics - at-least they give you a good laugh - not leave you feeling conned and red in the face.---------------------------Completely unreliable.After paring it with my Windows 7 desktop it works fine for a while and then just refuses to type anything. Sometimes it just goes bonkers and keeps typing a single character non-stop for as along as the machine is on!I contacted Iball customer service and the executive told me that the issue must be with my blue-tooth adapter.I took his word and wasted another 500 bucks purchasing a new adapter:https://www.amazon.in/gp/product/B005Z5HT2M/ref=cm_cr_ryp_prd_ttl_sol_0The only way to use this keyboard is to remove and "re-pair" it every time it malfunctions.This is the second time that an Iball product has turned out to be useless.Never buying any "iballs" again.

As long as it is connected it is a good experience and the keyboard is great with it's form factor. But it keeps disconnecting. You are typing and then you think for a while what to type and then you are ready to type again, and ... the keyboard is not responding. I have to turn it off and on again so that it works. Unless thin and light is your topmost priority, I will not recommend this. I am continuing to use this because no other keyboard is this thin and light in this range.
