I bought this tv in november 2014 from flipkart big billion day sale. It really is the best tv for the price.
It has inbuilt wifi and a quad core wifi. Videos on youtube are of very good quality and works without buffering. This is really fast tv and better than other smart tvs.it has also its own apps. I recently downloaded and played need for speed most wanted and it has very good graphics quality better than mobile graphics. Also it has active 3d glasses and I just love to watch 3d movies on tv rather than in cinemas
