Aren't you forgetting something?

Everyone is a bit forgetful now and then. Some people are more forgetful than others. Here's a gadget to help those with memory issues.

We've all seen those little keychains that beep when you can't find them. But those are usually only good for one lost item. This guy can keep track of up to four different items at once. Each device has a separate corresponding number on the base station. Just press the button, and find your missing object.

That makes things much easier, and leaving you with only one question to ask. Where did I set that base station again?
