    Does the trick!

    No gooey-ness or bad taste. Dispenses easily and works great with the blue light mouthpiece.

    Better than expected

    I saw this on social media and was doubtful at first. Started seeing a difference in about 3 days.

    Not bad.

    It took about a week before I noticed a difference. But so far-so-good.

    Snow is the best!

    I think it is amazing. Ever since I have been using your product everyone compliments me on how white my teeth are. The whiteness of your teeth can take 10-20 years off your appearance.

    I also use the whitening powder daily in conjunction with my toothpaste. SNOW is the BEST!!!

    Definitely worth it!

    I think it works pretty well, I ordered a kit 2 months ago and noticed a big difference. Ordered 2 extra strength pens. Pricey but totally worth it. I get a lot of compliments 😁
