I bought chromecast after watching the trailer on YouTube. I must say that this is must have product for anyone who owns TV and Android phone. You must have internet access before you could use chromecast(wireless router helps but not necessary).
Pros: Able to watch movies on TV, Play music, games, YouTube on big screen and control it with your phone. It’s fun and yon carry it with you when you travel and it can be used with any TV that has HDMI and USB port.
Cons: Doesn’t work without internet. Heats up pretty quickly.
4 stars because it doesn’t work without internet and I have to turn on my tethering every time I want to use it.
