Thanks for the input, guys. I ended up going with the beeper model over the GPS locator model - didn't see the need for IPhone location as the only place keys are lost seem to be in the house or somewhere nearby. Read some negative reviews of issues with the locator device - IPhone kept sending alerts indicating the keys were in Alergia, etc. Sounded like a more complex solution than we needed. Ended up going with this, hopefully we'll not need to use it often! Thanks for all the feedback, guys.
