Query: Not sure how this got produced...who signed off on it??

Folks, I'm sorry to say this is not a category where you can expect to get a decent piece for cheap...at least not this Jabra.The design is attractive, and HUGE kudos to Jabra for the inclusion of both AC and car chargers (YAY!!!!!!!!)...but it just doesn't work well at all. It's totally simplex, so it's like being on a two-way radio...only one side can speak at a time. On a desk, it's annoying. In a car, it's totally unusable.I know this item is tempting, because Jabra usually builds really good stuff and the price of this is half as much as its nearest competitor...but its performance is completely inadequate. Suck it up and spend the extra bucks on the Motorola HF820. It's VERY much worth it. The Motorola is ADEQUATE for the job; this one just doesn't cut it.Maybe the SP500 will live up to Jabra's excellent reputation, but for now I'm happy with my HF820.
