This thing has seriously been a marriage saver. We have one attached to my keys, my husband's keys, my husband's security badge, along with remotes and things we lose often like that. We have busy lives and I put things down without thinking and forget where I put them, so before we bought this I would do this to keys and my husband's security badge. We wouldn't realize we couldn't find it until right before he had to leave. The stress of not being able to find these two items would often cause us to argue. Many days were started with arguments because his security badge would be lost.
I decided to write this review after having used the key finder quite a few times, but particularly after a morning already filled with stress in which I accidentally lost his security badge. Now that we've grown used to having it around, I didn't miss a beat. I grabbed the remote and walked around the house pressing over and over and found it within 30 seconds.
This thing is seriously amazing. It works, and it works well. I would reccommend this to anyone, especially those with a busy mind like mine.
The only thing I would suggest to the manufacture, is to create a spot for a tab next to each color, or even on the back with the color or position reference to write what it goes to. But honestly, with how well this works, I am quite fine with creating my own code and keeping it with the remote.
