Summary: Works much better than others I've tried, but it's not the holy grail of bluetooth earpieces. Fair amount of dropped calls when using it as opposed to just using the phone (used both on the same daily commute for a year, so the only real variable is the device). Otherwise, it's just what I wanted.
Summary: I have it since 08/2011 and it is great for the price. Tested outdoors and limited to cancel noise of gusts (biking, walking), but for the price you can digest and go around with it by blocking wind with your hand/covering on ear.
