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

Went to use it for the first time and disappointed to find that the mouthguard led doesn’t stay on. Total waste of money and now hassle of trying to get it returned and replaced.

Perfect and nice effect

I had to stop using it.. it was like eating my gums up and turning them very sensitive.... and I used it as directed with the lip protectant stuff and everything... I kinda regret buying it but I just really want white teeth 😫

Works! I've tried whitening strips, gels, take home kits from the dentist, charcoal, peroxide, baking soda, etc, and NOTHING worked for me. I used Glo Brilliant and within 2 uses the difference is evident! I posted some photographs so you can see. My teeth were on the 10 level and now they are about a 3 on the color shade chart! I used the system for 5 consecutive days at 32 minutes each time, I think one day I used the system in the morning and again at night 🌙 🙃. My teeth still have a natural yellow hue to them but they are much lighter. Oh, I have a habit of biting the mouth guard. 😬 Try not to do that, just relax your mouth while you wear it. My teeth had some stubborn plaque looking stains, but Glo removed them! Make sure when you apply the gel you get in between the teeth. I read somewhere that once the gel is opened its only good for 7 days. I used TWO gels in 5 days. The instructions recommended to use a new coating of gel after each 8 minute round but I reapplied the gel after every 16 minutes instead. The gel barely has a taste to me. I feel like I look like I take good care of myself now, which I do! It's a satisfying and elevating feeling. I like my Self better and feel closer to my Self for having used this product.

Don’t waste your money. Maybe improved a shade over the course of 9 or 10 treatments. Still enough material for another week of treatments but feels as if I didn’t even use what I did.

This system definitely works to whiten teeth. Everyone's teeth are different and I imagine everyone gets very different results but it isn't snake oil - it does do something! I have very sensitive teeth and have steered clear of whitening for years. During the pandemic I've found myself drinking a lot more tea and that has really discolored my teeth and was starting to get embarrassed about them. I bought this device since so many people say it's good for people with sensitivity.I used the device as instructed. It never bothered my teeth at all. It did start to irritate my gums a little, but nothing too bad and only while I was actually doing the whitening. What I did find, is that I was incapable of keeping my tongue completely away from the whitening product (especially because there's a lot of saliva build up and spitting involved). It really hurt the tip and side of my tongue on the days I was using it. I had to stay away from certain foods which was a bummer. After the recommended 5 days of use, my teeth were absolutely whiter. I didn't have Hollywood level whiteness, but they were a lot better than they had been and I was no longer embarrassed. I could have gone on and done more whitening, but my tongue couldn't take it anymore. I will probably go back in a couple of months and do the process again.I feel like I can definitely recommend this to people with sensitive teeth. I think everyone's whitening level will be different (some might be more or less than me) but it does work and depending on your level of tolerance for the whitening product, you can likely get to your desired level.

I've buying products from Amazon, from many years ago over 30+ products and never had an experience like with this product. I received this product and only lasted only 2 minutes working, after that it stopped, I tried to charge it and never work again. Has been my first experience with a damaged product and impressed me, because I tried to spend some more money respecting to other products similar but It came damaged despite the price of this product.I just tried to get relax about this product and tried to contact the Amazon customer service to ask for a new one, and they commented me I’ve to return it when I check the price from my country to send it and the price of the shipping to send it back, it is almost the same cost of the product itself. I feel that if companies like Amazon or other such GLO that sell a product of a higher cost respecting to others in the market, they should try to find a better solution for cases like this. I understand that there are policies, but in the end, everyone is affected at the end.Regarding GLO Whitening product, I recommend others to avoid buy it the product seems so beautiful, modern, and elegant; but it doesn’t work. I’m attaching a video about my dysfunctional product, it is full-charged and I'm trying to turn it on but doesn't work.
