Supertooth II Portable Handsfree is designed primarily for the car by BlueAnt which is an Australian based company.

The beauty of this DSP Supertooth II design is that flipping down the microphone turns on the device and answers the calls. If the Microphone is kept in the “down” position, calls will automatically be answered when they come in. Your hands never have to leave the wheel – which is the idea behind “hands free” design.

This kit comes with two magnets sun-visor clips. Which means that you get a spare one or you could keep one for home. This clip is excellent for car or SUV with slimmer sun-visor and it attaches firmly. As for bigger thicker sun-visor, you have to physically pull the clips before attaching it firmly on the sun-visor. Frankly, I have not seen any devices that attached so firmly magnetically on the clip. 

The volume control knob is easy to use and view being the old fashion type who do not like the up and down button.
