Review on SmileDirectClub Trackable Retainer/Aligner Case – Find and Locate Your Smile Essentials with Tile by William Lin

Pros: - I only got this lock case because it has a tile tracker built into the floor. The tile connects easily to my phone and like any tile device, can be activated to play a custom sound for easy localization. I also love how colorful it is so it's easy to spot on a restaurant table or just lying around. at home. - The Invisalign retainer fits snugly into the rubber-lined case. - You can use the sliding floor mirror to check that the retainer is in place. - The lid opens easily but stays closed when not in use. It won't open accidentally. Cons: - There's no way to replace the Tile's battery, so it's disposable, and I don't like replacing and throwing out the whole thing if the battery eventually dies. - I wish there were other colors besides purple. The above review is for the Smile Direct case with integrated tiles.
