I currently use a Plantronics Voyager 510 and love it, except that it's too cumbersome to quickly put on when answering a call. I saw the Samsung WEP200 and had to try one at this price (&lt;$20). I'm getting good reports about the voice quality and all features work as described. The ear hook needs to be positioned differently than shown in the instructions, more like nine oclock orientation for use in the left ear, but fits very securely once setup. The killer feature for me is that I can answer a call on the fly when wearing sunglasses just by plugging the WEP200 into my ear, and I could not do that one-handed with the Plantronics. The charging case is also a convenient case when stored in the car's console. I'm well satisfied so far.
