Detailed Review:
-------------------

I tried several of these type of devices and this one seems to be the best quality in terms of construction. The bezel is sturdy enough for what it is and the screen is big and bright making it easy to use. The only flaw I found is the knob to move between options is very sensitive so you often scroll past the option you want.

Like most of these devices there is a constant clicking sound causing feedback during audio playback. It occurrs in any mode (aux, USB, Bluetooth). Unlike most devices however, the feedback with this device is not as loud and fairly tolerable.

I amd not a frequency expert but I have done some research. I believe this feedback is due to either the Bluetooth modlue always searching for a device to pair with (can't disable it) and polluting the FM signal, or the FM transmitter is weak because the feedback almost goes away completely when you put your hand over the device.

Despite the issue with the background noise, I would recommend this product because it is easy to use, looks nice and is the least noisy that I've seen so far.
