Product Feedback :
I was using a reliance netconnect+ ( corporate scheme ) 10gb usage for Rs. 730/- which is 2g connection and net speed is very very slow.. If a video is 3 minutes, i can able to see the video in 6 - 8 minutes with every time it buffers. Got irritated with the reliance device..

Where is the fun when everything loads like in micro seconds? I like to wait like 10 minutes before I hear a song stuttering and playing for a second.

So my life is slow again. Yay!

Easy to use UI. WIFI. Good speeds. It's a good product. But it gets heated very soon.

It works fine and the speed is great in aircel 3G, not yet check with 2G connection.
One thing the wifi is in beta and disconnect other devices after some time.
Hope it will work fine if update is release from manufacturer.
