I bought this TV for about INR48K in Oct 15 on Amazon.in and so far am happy with its picture quality. Its doing very good w.r.t picture quality of SD and HD channels off Videocon D2H and bluray player effortlessly. Its android interface allows you to browse net, social media, you tube etc ..
The sound is a bit low (as expected with slim TVs) but not bad. I am using my Wharfedale Vista 100 soundbar with this and the audio part is taken care of with it
I thought its a good deal given its spec and 3 year onsite warranty it came with at no extra cost.
Agreed, it cant do 4K at 60fps but can handle 4K at 30fps, i dont care about it as I dont have content of 4K available at the moment and i will be happy if this TV functions for next 3-4 years .
A future proof 4k tv with similar spec could easily cost you 4 times more
