I recently purchased this from an overseas retailer and promptly returned it after 1 day of use.  It seems to be a great concept - love the setup (charger, small footprint, fits snugly in the ear) but the static and distortion made the device practically unusable.  The retailer I purchased it from has offered to replacement - as it is coming from overseas I don't have it yet but will post again with an update once it's arrived.
