By the "specs", this device offers me what I want; freedom from holding my brick (cell phone) whenever I need to use it (often). After using it for about a week, here's my thoughts;Sound quality: people can hear me better than I expected. The speaker is pretty decent, and I can hear most people.Feel: pretty comfortable (with the conformal ear piece), but akward at first. It takes some getting used to. It's extremely uncomfortable without the conformal ear piece, to the point of being totally unusable (see below).Craftsmanship quality: poor. The ear piece comes off entirely too easily. It can be knocked off by brushing against it. Since the device is on your hip, this happens all-the-time. The first several days I was always able to find it. Within one week it was lost. I was on a business trip, and although it comes with an extra ear piece for each ear size I didn't have one with me. The device went into my bag for the duration of the trip. In addition, the second day I had it the "boom" (headset) part of the device came apart. There is a small plastic cowling that covers the wires leading into it that just popped off. It seams like everything on this ear-boom is [poor quality] and comes apart too easily. I wonder if the wires will pull out next.A keeper?: not quite sure yet. I'm going to keep using it for another week or two before making a decision. It does offer me what I want. I just have to worry about it all the time, which is not what I want (I have other things to concern myself about, for example, answering the phone).
