I really wanted it to work.
I drink two cups of coffee every day and I definitely needed something to help me with my coffee stained teeth. I applied them for 2 weeks and didn’t notice a difference in my teeth as far as being whiter. I also noticed a bit of an increase with sensitivity, which tends to happen with most teeth whitening. It is nice that you can take it on the go but isn’t really helpful if the product doesn’t work.
