I have used it. Its a bit slow.
Also - since it is an android device - every time your power goes out, your time gets reset and every app stops working. So make sure if you do buy it, you connect it with back up power.
I would also prefer chromecast and using an actual PC instead.
Also - go for smart TV Abuzer Bhai. Kin chakron mein parr gaye hein? :p
