People forget things. People misplace things. You do it. I do it. We all do it. No matter how good our memories are, we have lapses from time to time. If you’re also a Potterhead then check these trackers out. The Harry Potter Foundmi Trackers are the Bluetooth trackers straight outta Hogwarts.

These trackers are styled to look like one of your three favorite child wizards, Harry Potter, Ron Weasly, and Hermione Granger. They’re Bluetooth trackers that you simple attach to whatever you want to keep track of.

They work with an app. If you can’t find your item, just pull up the app and push the notification. It will play a little jingle to help you find it. The batter last for up to six months. You can get one for $32.99.
