GLO Science — GLO Classic Brilliant Teeth Whitening Device Kit w/Patented Warming Mouthpiece and Blue LED Light Technology — Designed for Sensitive Teeth, White Device

The GLO Brilliant Teeth Whitening Device is a customizable and effective teeth whitening option for users. The kit comes with 10 teeth whitening GLO Vials for 10 days of whitening with each session being 8 minutes long. Users can customize their treatment plan, completing the 5-day treatment (four 8 minute sessions in a row each day for 5 days) every six months or completing 1 day of whitening each month for maintenance between full treatments. While the device technology is the same as what is used in dental practices, the strength of the whitening gel that is included in the dental practice version is higher than the one in GLO Brilliant Teeth Whitening Device. Therefore, the device version may not be as strong and effective as the one used in dental practices for individuals with severe staining or discoloration. Overall, the product has received mixed to negative customer reviews, ranging from issues with the device's battery life to not seeing any noticeable results on the teeth. Moreover, a few customers reported hardware malfunction in less than a year of use. However, several customers have stated positive results and recommending Glo to others.
