Query: Do not purchase the Supertooth Light, instead buy the Supertooth 3.

Do not buy this product. The spring loaded retractible microphone piece that you push in & out to turn unit on & off broke not on one but 2 of these units. BlueAnt was kind enough to replace my 2nd Supertooth Light (STL) with a Supertooth 3 (ST3). So just buy the ST3 & save yourself the headaches of having to deal with the vendor & manufacturer a couple of times. The mic is built into the ST3 model. Paring is simple, auto phone book transfer, auto voice recognition (no training of unit needed). True handsfree with voice command answer. Great volume & sound quality. Also, the option to move from vehicle to board room or conference room (or another vehicle for that matter) is a plus.DO NOT BUY SUPERTOOTH LIGHT! (I rate the Supertooth Light 1 star). You've been warned. Instead buy the Supertooth 3. (I rate the Supertooth 3 (4 stars).
