The unit is compact, very light and rugged. The battery lasts as long as is claimed (better than a week in standby, several hours under constant use). It comes with a detachable cradle in which the curved ear piece may be replaced by a short wire and in-ear button speaker. I use this latter form and am very happy. What becomes the base unit sits in my shirt pocket (the cradle has a clip that points the microphone up) and the wire has a small clip midway to keep the wire out of my way. The unit communicated and matched up to my Sprint Samsung phone with no trouble on the first try. The sound quality is a little lacking (hence the 4 vice 5 star rating) but is clearly audible if the ear piece is in place correctly. The volume is sufficient if a tiny bit low. If your phone has voice command (mine does), the unit works well, my phone asks me to confirm my choice only about a third of a time, which matches with when I don't use the headset. I have spent over $150.00 on Motorola products claiming to be much better - both are in the garbage now, being completely useless.In short, this is a good unit and for 10 bucks, a deal to not pass up!
