This is just to alert anybody buying Byond tablets. I bought a new tablet (Mi-book 1) whose screen just went blank, sent to a service center in Navi Mumbai, Vashi called Kaizer Telecom. Its been almost 2 months since it was given and nothing has been done.
I contacted Byond customer support who told me that the tablet will be fixed but absolutely no progress.
Think twice before buying!

touch is not at all working properly in many of the area of the screen. Touche screen is the only input we have but it is not working as expected , and it does not have 4 GB , It has only 2GB + 512MB storage .

tablet is good at its price level but without calling facility is like dullsome so no worth to buy...you have to purchase supported dongel along with this so think twice be vice.........7 inch screen is great at gaming experince

I am fully satisfied with the tablet.WiFi ,android apps,usb dongle connectivity ans so on....Mainly for watching movies and videos in HD ,apps,storage.

VERY NICE TABLET..

Probs:
1.Hangs sometime
2.No sim support (Its Ok for the less cost)

Received it today , wonderful tablet for 3999 , you wont get a better tab at this price .

I have used the byond its is great.... only problem is battery backup but it can also be improved by reducing the display brightness, Using headphones.
For the cost of 4000 the features in Byond tab is great to use

You must know what u r buying
now consider reading specifications ass follows

>worst audio quality
>front camera but no face unlock
>procesor is 1008mhz....and remaining 200 mhz..? god knows...!
>poor gpu which makes it limited to gaming of angrybirds only...!
>when show touch option is allowed...then we will see that touch is not where it should be...
>hangs a lot if not restarted daily
>antutu benchmark is below 3000...

lastly not worth buying as providing 3d glasses with a tablet doesnt ...

Dont worry about the brand. Not suitable for heavy gaming, or big applications. But a very handy tool. Never expected a 4k tablet can give me so many features.
Only downside is the battery life, but if you use your tablet primarily indoors then this is your pick
