I am using Datawind Ubislate 7W Tablet from last 5 months and the experience is too bad , There are lot of problems in this Datawind product.
The speaker is too poor. Its volume is very low and unclear.Even the person standing next to you is not able to hear a sound.
The cameras are very bad .Some time they cant detect your face . And at night you cant see anything.
The bodys paint quality is very low. It is going light day by day.
The display is getting yellowish day by day.The widths is big as compared to others.
The battery backup is to short , if you charge it 100% then it will only hardly work for 2 hours.
The overall experience is to bad.It is worst product .
