Help please
I don't know if I'm using it right. I just got it a little bit ago, and immediately went to test it. The instructions say that I'll hear a beep after 5 minutes, but it's already been past that

Quick whitening
[This review was collected as part of a promotion.] I received this to try in exchange for my honest feedback after using for weeks. The process of it is very simple. Download the app it states, use the cord provided, and connect the device to your phone. It has a timer for each time it's used. The gel was easy to swipe on teeth. The device is flexible and easily fits in your mouth. After testing for some weeks I've noticed my teeth have definitely lightened some shades. I'm impressed with how simple but yet effective this device is. I believe it's the closest you can get to whiten your teeth in an over the counter product. I'm happy and will buy more of the serum. #hometesterclub #colgate

Definitely worked after 7 days
[This review was collected as part of a promotion.] While I didn't see any noticeable after 3 days I did see a difference after 7 days. The change was noticeable and others complimented and also noticed the difference. I would definitely recommend and will continue to purchase.

So so.
[This review was collected as part of a promotion.] I was excited to try a whitening system with a light as I've used one in the past and it worked great. This one didn't quite hit the mark. First, painting your teeth with bleach after you brush them can be very difficult as your mouth tends to water more after brushing. I tried to combat this by brushing 10 minutes prior, but it's still hard to get your teeth dry especially the bottom ones. The next issue was the mouth piece. It has 2 little tabs on the inside that are to bite on to keep the mouth piece in place. I found myself constantly adjusting it to keep it straight. I feel like the tabs were too small, but may work for someone who has a straighter smile. The idea of using your phone to power the device seems good in theory, but not as convenient as a chord free alternative as you would need to hold your phone or have a pocket if you wanted to move around. I didn't see enough of a change in the whiteness of my teeth to consider the work to be worth it.

Definitely see a difference
[This review was collected as part of a promotion.] This is my first time using the Colgate Comfortfit LED kit and I absolutely will be using it again in the future. It was easy to use and the results were right there when I looked in the mirror with each use. I applied the gel pen and then the LED light at night, right before bed, so sleeping with the gel wasn't a problem. The following morning, I brushed my teeth and made sure to get any remaining gel off, and you could definitely see the product working. I did experience some tooth/gum sensitivity, so I made sure to give my mouth a break in between treatments. Overall, I am very pleased with this product and plan on keeping a kit in my bathroom cabinet.

Great way to whiten your teeth at home
[This review was collected as part of a promotion.] The product is very easy to use! It it compatible with USB-c and iPhones- yay!! The gel is easy to apply directly on my teeth with the soft brush. It gets into tighter spots thanks to the brush. Then I really love that ai don’t need to set an alarm or look at the time because the Colgate device turns off automatically after 10 mins.

Easy to use
[This review was collected as part of a promotion.] This is the best teeth whitener I have used! It is so convenient being able to plug it into my phone. The gel is easy to apply and doesn’t make my teeth feel sensitive at all. It’s quick and easy to use and the results are amazing! Highly recommend!

Colgate Comforfit LED
[This review was collected as part of a promotion.] I have tried this Colgate Optic White ComfortFit LED whitening kit for 10 minutes per session and have noticed quite a brightening difference in my teeth. The whitening LED light is flexible and molds to the curve of my teeth for a comfortable fit. The LED light had teeth grippers on the back so you can hold with your teeth while whitening sessions. It also came with a case to cover the LED light for sanitation. 2 adapter ends are provided types, & iPhone adapter for easy connection. The Colgate Connect app was easy to download and extremely helpful. The directions were simple and easy to follow. I also found that the whitening paste didn’t have a bad aftertaste and the paste wasn’t think nor have an overpowering scent that was unbearable like other kits. The applicator came with an easy to use brush for easy application with complete coverage of each tooth. Another plus is the device is compatible with iPhone & Android as well. Truly happy with my new Colgate Whitening LED device.

Great product
[This review was collected as part of a promotion.] I’ve been using this teeth whitening kit for a few weeks now and overall, I’ve had a pretty positive experience. The instructions were clear and easy to follow, and the process itself is super simple. One thing I really appreciated is that it didn’t cause any pain or sensitivity, which has been a problem for me with other whitening products in the past. I actually did notice a difference in how white my teeth looked after a few uses — definitely brighter than before. So in terms of effectiveness, it worked for me. One thing I really don’t like is the shell or crusty layer the treatment leaves on your teeth afterward. It can be hard to remove completely with a toothbrush, especially in hard-to-reach areas. That part feels a bit off-putting and could be improved.

Maybe my teeth are already white?!
[This review was collected as part of a promotion.] It’s been around 15 years since I’ve whitened my teeth, although is still say they’re fairly white but could use a freshening so I was considering consulting my dentist for whitening options. Previously I had a two trays that my dentist custom fit to my teeth, and a whitening agent that was only available to a dentist. I remember being able to pick the percent of whitening and gradually increasing to get my desired shade of white. This option was not cheap as they trays alone cost several hundred dollars, so I was excited to try this product. I think it’s nice that the led light plugs into your phone, this makes it easy to use the light anywhere and not trapped to sitting next to a wall. The mouth piece had an odd fit, I felt like I had to hold it with my hand to keep it where it needed to be. I didn’t like how hard it was to get the whitening gel off my teeth, and sadly I haven’t see any results. I don’t think I’d recommend this product.

Works great! Whitest teeth ever!
[This review was collected as part of a promotion.] I was nervous about using this because I have accidentally burnt myself before from using a tooth whitening product that was similar. I was happy to find out that this was gentle and easy and no burn! My teeth look whiter and I can’t wait to keep using it.

Easy to use whitening kit!
[This review was collected as part of a promotion.] I really like this kit! The Colgate ComfortFit LED Teeth Whitening Kit has been amazing for my smile. One of my favorite things about it is how convenient it is, it plugs right into my phone (there is a lightning and a USB-C connection port) , so I never have to worry about recharging anything. That makes it super easy to use anytime, anywhere. After using it consistently for over a week, I can already see a noticeable difference in the whiteness of my teeth. The whitening solution doesn’t have a bad taste, which makes the whole process even more pleasant. The kit is very user-friendly, and I experienced zero discomfort, which was a huge plus for me. Overall, this is a really great product. It’s simple, effective, and comfortable, its everything I was hoping for. I'm excited to keep using it and see even more results!
