We received it as a shower gift. We then followed the instructions to attempt to optimize the performance using all combinations of options available. No matter what we did, it's way way below our expectation - basically, there's close to no picture and the audio is too bad. We couldn't believe a product with such a low (or no) quality could be available in the market. We wondered if it was just a defective item so we tried to have it replaced online but were told that it's not available from the supplier. Not sure if our item (n=1) can represent the product but if it does, stay away from it!
