My tech life:
I recently purchased 2 of these little guys for use with my Samsung Galaxy S2 I777 and my AppRadio 2 double din car stereo. The good news is, this item worked well with my Galaxy S2 and it was recognized by all my older LCD televisions. The bad news, this item did not function with my Galaxy S3 which it was not designed to work with. If you own a Galaxy S3, do not purchase this device. You can buy the official Samsung Galaxy S3 MHL adapter from Samsung’s official website for 24.99. Take a look at my Samsung Half off accessories tutorial for details on how to get half price off any Samsung accessories under $50.
Overall this is a poorly made clone and I would advise you not to buy it. The device will tend to get warm and not function over a period of time and regular use.
This device does not function with the following devices:
Galaxy Note 2
Galaxy S2 – not 100% compatable
