I've been using the Colgate Optic White ComfortFit Teeth Whitening Kit for the past month, and overall, I'm quite pleased with the results. Pros: Effectiveness: After a few uses, I've noticed a significant difference in the whiteness of my teeth. The LED light seems to amplify the effect of the whitening gel. ComfortFit Design: Unlike other kits I've tried, the mouthpiece in this one is quite comfortable. It fits well and isn't intrusive, making the 10-minute sessions more bearable. Easy to Use: The whitening pen makes application straightforward, and the LED light is simple to operate. Cons: Sensitivity: While not a deal-breaker, I did experience slight gum sensitivity. It wasn't severe, but if you have sensitive teeth, it's something to consider. Overall, the kit delivers on its promise for whiter teeth, but the battery life and potential for sensitivity hold it back from a 5-star rating.

I have used the kit 4 times - I skipped a day - I forgot. Here's what it's really about - it's not what I expected. 1. You have to have your phone to charge it. You can also plug it into a charging outlet - it does not have it's own power source like most. You do the light for 10 mintues: You turn it on and it runs for 5 minutes and beeps to let you know its half way - it runs another 5 mintues and beeps and shuts off. None of that is in the documentation. I kept taking it out at the 5 minute beep. 2. It's a paint/film, it is not a gel that you rinse off after. 3. It's hard to get an even layer with the applicator. 4. You can't tell how much product is on the applicator and if you're using enough. 5. Sometimes you get it right (I guess) with a thin layer you can't really feel after it dries. 6. Other times you get a big glob and you can feel a gritty layer on your teeth. 7. The film is recommended to stay on your teeth overnight for best results. 8. The pen liquid has peroxide and the blue light just accelerates the peroxide chemical process to bleach your teeth. 9. The gel to use going forward is expensive. After the pen is empty, I think I'll just brush as usual, then brush on a small amount of peroxide and use the light. Only a few times a week. Too much peroxide is not good and will burn and damage. Maybe I'll just use a peroxide toothpaste and then the light. 10. Right now, I have what feels like nail polish on my teeth and it's crumbly and flaking off periodically, causing me to have to spit it out - which is annoying. But my teeth are noticeably lighter. I just won't be using the liquid pen anymore. 11. The mouth piece, however, is the best I have ever come across, so I would like to keep using it. You just can't hold it in your mouth like other blue lights and walk around and do stuff - you have to take the power source with you.

The Colgate Optic White Comfort Fit Teeth Whitening Kit is a game-changer for those looking to brighten their smile. This kit comes with an LED light and whitening pen, making it convenient and easy to use. What's great is that it's enamel safe, so you can whiten your teeth without worrying about damage. One of the coolest features is that it works with both iPhone and Android devices, allowing you to track your progress and achieve professional-level results from the comfort of your own home. Say goodbye to stains and hello to a dazzling smile with the Colgate Optic White Comfort Fit Teeth Whitening Kit!

My unit worked fine the first couple of times I used it but then I would have to play with it to get it to come on and then it didn’t stay on for even 5 minutes much less 10 and now it doesn’t work at all and it is less than a year old and only used a half dozen times. I would not recommend buying this unit.

In the past couple of years I went to two separate dentists to professionally whiten my teeth and it didn't work. I was told that professional whitening didn't work for everyone and I was one of the small percentage where whitening wouldn't work. I used this Colgate whitener over the recommended 10 days and noticed an improvement in the color of my teeth though. My particular situation: I have a crown in the front that was put in over 15 years ago. My teeth got stained over the 15+ years so the crown looked whiter than my other teeth. Although my teeth didn't whiten to match the crown there was a noticeable improvement and the crown didn't stand out as much as it did before. I plan to buy additional pens and continue to use this whitener in the future.

I really liked this whitening system, especially the light. Give yourself a month to see full results, some might see it sooner than other but the first session you will see improvement.

Don't seem to even lift surface stains, whitening toothpaste does a better job.

If you use it for 10 days as instructed, you will see a difference, but the pen doesn’t work well or last long. There’s no good way to clean the pen without it ending up a mess.
