I love this thing. But it has SERIOUS faults.Good stuff:1. Thin and VERY light. This is a MUST for any handsfree, but still must be said. The H700 is so light that I *often* forget I'm wearing it.2. comfortable. It hooks over my ear and, again, I often forget I'm wearing it.3. Stable and steady. The unit has only fallen off my head once in about eight months' ownership. The thing holds on so steadily that I wear it while bicycling.4. standard USB charger.5. reversible (for left or right ear)6. Folding in the boom turns the unit off (for storage, or your pocket, or whatever). This is a really useful feature for me because I use a link-to-cell phone system at home and I need the H700 to shut down before my cel phone will connect to the home system.Detractors:1. battery life. It's questionable to begin with. This is not a big deal for me as I generally don't need it for more than a couple of hours at a stretch, and just about everywhere I go has a USB charger.2. signal strength. This is obviously designed for you to wear your phone on your person. If ANYTHING gets in the way of that, it becomes unusable. For example, I generally put my cel phone in a pouch under my bike saddle when I bicycle. When this happens, the H700 can answer calls, but people usually cannot understand what I'm saying, even when I'm stopped on a calm day.3. longevity. At 8 months, I am beginning to notice significant battery degradation, and the chrome finish is beginning to flake off-- not merely an aesthetic concern; I assume that with the finish goes some of the weatherproofing.BOTTOM LINE:$40 is a good price for this unit. Knowing what I know now, I don't know that I'd have paid $90 again for it, but the current price seems like a bargain for this little gem.
