Title: Battery life isn't as claimed
Review: The thing works just fine, but the device claims to last up to nine months on a single battery. I am currently changing the battery at a rate of once every 7-14 days...My first clue was seeing a cat standing right in front of it and not flinching. Turned out the battery was dead after one week. There was no other 'traffic' coming into the yard and it's out of sight of trees etc.
