I have to reconnect lock to my phone'b bluetooth almost EVERY time.  And the auto unlock, which is the feature I bought it for, only works about 90% of the time.  HOWEVER, that 90% of the time is sure nice not to have to fumble for keys!  But inevitably, everytime I have my hands full, that seems like it falls into the 10%, which is frustrating.  I think the August folks will keep updating the app and firmware though and one of these days, it will be more reliable.  I do like how it fits over the existing lock and you can still use your keys if you have to.
