Wearing braces for 1 hour is completely uncomfortable and ineffective in the whole process, as you lose all the whitening material due to the saliva running during this time.

Misleading. It creates temporary whitening effects immediately after rinsing.
After continuous application for 7 days, no difference!

I tried it for the first time now. As a first test, I believe I noticed a difference, for now, I am very satisfied.

I didn't see any difference and in fact it whitens the teeth in their corners that are thinner, so it's like they have patches. Also, one hour with the mouthguards that are very uncomfortable is an exaggeration. If you say that you will use them first one and then the other (because the mouth doesn't close with both mouthguards and saliva runs) you need 2 hours ☹️.

Contrary to other similar masks, you have to wear it for 1 hour instead of 20 minutes, and it is very uncomfortable. It doesn't make a big difference and it also leaves white marks.

I applied the product (literally and for 7 consecutive nights before sleep) only on my upper teeth, because both my jaws together were causing me nausea. I thought that this way I could compare the difference and... guess what! There is absolutely no difference in tone compared to the lower teeth where I didn't apply any product at all. It was a waste of effort and money!

It does the job, my teeth already look whiter from the first application, same as my friend's who we bought them together. I would buy it again, because even the teeth whitening I had done at the dentist's office and paid much more money for didn't last. The strips are not the most convenient, but for me, it's worth it.

I used it for more than 7 hours, because there was plenty of product left, which is a positive thing. (Besides, the acidity content was not very high, so it doesn't cause any issues). I should mention that I neither smoke nor frequently drink coffee, wine, etc. It does slightly (!) improve the appearance of teeth, making them just "naturally yellow" but never white. As for the negatives, I would mention the whole process... the strips are quite big, tiring in the mouth, and they don't adhere completely to the teeth, resulting in a lot of product being lost during consumption! ???? The deep truth, after trying several whitening products, is that the best and most dramatic results are achieved through professional whitening at dental clinics! Another usefulness I found is that it would be excellent for maintenance, once in a while after a dental whitening! That's it ☺️

3rd day that I use it and the results are incredible... I recommend it to everyone, it's worth every penny and more

Compared to other products I have tried, like iWhite 2 which did nothing, this one actually works!

Much better than i-white. It does the job if you use it as instructed for 7 days, and the tubes lasted me even longer for additional applications. It was very difficult to do both the upper and lower teeth at the same time because the trays are bulky and you can't keep both in for an hour, so I suggest doing the upper and lower separately for better results. If you have a major issue, don't expect miracles or long-lasting effects
