Review on Portable Pink Retainer Case with Timer/Alarm - Dentist Recommended by Irma Brown

I understand that this product is a child's invention, which I think is great, but it doesn't justify a child's design. The screws holding the timer are visible inside the case. When storing Invisalign or retainers, moisture inevitably builds up and the screws are now rusted. I'm uncomfortable storing what I put in my mouth in this environment. The design of the case makes thorough cleaning impossible without damaging the timer. Unfortunately I used this case for a month before judging it and now I've missed the return window. Please don't waste your money on this item until they fix the rust problem with rust resistant screws or an upgraded case design.
