The Nulaxy Bluetooth FM Transmitter came well packed in a sleeved retail style box and includes a user guide and a short 1/8th in. audio cable.  The device is constructed mostly of plastic and utilizes a 12v plug to support it.  A flexible arm is attached to the plug and extends out to the main portion of the device.  This design is convenient and will work in most cases but I suggest looking at the picture to determine if it will work in your vehicle.

On the top of the device you will find a 1.5in screen and seven buttons.  The buttons can be used to cycle through different FM frequencies, play, pause, stop, answer, end, skip tracks, and control the volume.  If you are used to the controls on other Bluetooth devices, it will take no time at all to get used to the ones on the KM20.  The device also features an aux. in/out port.  This can be used to take advantage of the aux. in on many newer cars for better than FM sound quality as well is channeling audio from a device that does not have Bluetooth.  The KM20 also features two 2.1A USB charging ports which is an awesome addition.

Overall the KM20 FM transmitter is a well rounded device that is easy to use, performs well, and is loaded with features.  If its design works in your vehicle, I highly recommend it.
