Fantastic. Only used 3 times and I see a huge difference in my teeth. Would definitely recommend. There's instructions for how long to wear it. I use it every other day, 20 minutes a day + teeth whitening toothpaste. I also use sensodyne as your teeth become sensitive, which is why I only use every other day.
Looks just as described but I haven’t yet used I’ll leave additional feedback when I do and the seller was so nice
