As a Vine member, I received this product in exchange for my honest review!This thing has been a lifesaver!! Me and the ol lady get up every morning and argue about where she put the keys the night before.. Panic sets in as the keys are lost, time is ticking away, going to be late...Then, we got this wonderful key finder. There are four fobs, batteries for all, and a remote and stand. All you do is press the color of the key fob you’re trying to find, and it sends a wireless beeping sound. Amazing that something so simple makes so much sense! I can’t attest to the battery life yet, as I’ve only been using it for a week. Haven’t had to use their tech support yet, but will update if necessary.
