I purchased this little converter for my Samsung 3D TV. It works great. The best part is that unlike other converters in it's price range - I can now receive all of the TV channels without having to hook up an extra antenna which was costing me $80/month before.

Ex Output:
Good Review

The main thing I got out of this book was to take note of the difference between a'market' and what an artist thinks a market could be. While the writing is fairly competent, it can not be taken as completely self-serving. It seems to suggest that if you give them enough money they'll keep coming, but they won't. There are some interesting ideas there, but they're scattered amongst the clunky writing.

For the price and quality - it is a bargain. It's been working on my Samsung TV every day for 6 months. Easy to use and works fine. Not sure if all bluetooth receivers can be this good. Only con I could think of now is: It picks up Bluetooth from other devices when I'm not near it. If it does that, then this receiver will get 5 stars. The only reason it's 4 stars is because there are some things with its functionality. It just isn't perfect....
