I have a 32 inch sony tv and being from middle class I could not afford smart tv worth 50k. I found chormecast to be tha best alternative. I have both generation chromecast. The gen 2 is much better then gen 1.
Pros:
Available at cheap price at 3399Rs.
Avaialbe to all android phone.
Easy to use and fast.
Can stream any video from phone to tv.
Supports most of the tv that have HDMI port.
Cons:
Gets hot a little bit and there is nothing to compalin about.
Instead of going for high end smart tv buy a normal big screen tv.
