I saw reviews with 1 star, others with 5, and I couldn't make sense of it. In the end, I got the kit and, in a few words, it does what it promises. It doesn't work miracles, but for 30 euros it slightly whitens yellow teeth. If you don't get the mouth trays right the first time, you just reheat water and do it again, because once you heat them, they return to their original shape. It's important to suck them in so they fit snugly around your teeth. During the process, I produced a lot of saliva in my mouth, so I kept it in for 20 minutes. I recommend them for before weddings, christenings, etc. Obviously, they won't do the job a dentist would do, who charges around 270 euros (mainly because he makes custom trays). So, it's a good quick solution to use every once in a while to keep your teeth as white as possible.

I used it for my wedding and it did its job just fine. The result did not last more than two weeks but for what I wanted it was ok.

It does nothing. The only good thing I found is that the splints can be useful during sleep, so that the teeth do not grind against each other.

Don't waste your money for nothing, there is absolutely no comparison with the results you will see from a good dentist!

There is really no relation to what is advertised. The only thing it does is create temporary discoloration on the teeth (not even uniform, but creates white spots) for a maximum of 2-3 days. Afterwards, the teeth become yellow again. Therefore, there is no need for someone to waste their money and burden their body with unnecessary chemicals

The product is fine. It says to leave it on for up to 35 minutes, but I left it on for an extra 10 minutes. From the first day, I noticed some difference. Although it will be difficult, I will try to reduce coffee intake for maximum results. With this price, it's worth trying!

Very good product for its cost for what it offers. In one week, my teeth became 3 shades whiter. I didn't have any difficulty fixing my braces. No side effects. Obviously, it's not like going to the dentist, but for someone who can't afford to spend 150-300€, it's the best solution for me!

It does not cause any discomfort and has a refreshing taste, like toothpaste. I couldn't adjust the braces myself. Especially on the molars, they fit tightly and do not fit properly. Immediately after use, some white spots and discoloration appear, which fortunately disappear after a few hours. Other than that, I noticed a difference of about 2 shades

With 45 minutes a day for 10 nights, I saw my teeth approximately 4 shades whiter. I haven't felt any discomfort or anything strange. It's obviously not a dentist whitening, but it's definitely value for money!

It's not bad. I definitely had higher expectations, but I used it for a short period, only 4 consecutive days, and sporadically afterwards (meaning not 10 consecutive days as recommended), and I noticed a difference. I would say that my teeth are even whiter than before (3 months later), and I still drink coffee and red wine. I think it will work for some people and not for others.

Quite a good kit for its price. The good thing is that you make the mouthpieces yourself and they take the shape of your teeth. I put gel the size of a lentil on each tooth. I avoided anything with dyes and left the LED on for about 40 minutes every night before going to bed, and the result was four shades lighter! I kept the mouthpieces and the LED to buy replacement gel in two months.

The cases are very thick, even if you adjust them as best you can, they require a lot of material to fill. It is better to make cases with a specialist and use the rest. Because they do not embrace the teeth properly, they only whiten certain areas!!

Very good. Impressive results, better than a professional whitening I had done, and without burning my gums or having any side effects. I followed the instructions exactly and it removed coffee and color stains during use

I saw very good reviews and decided to give it a try. Personally, it didn't work for me at all. I followed all the instructions and used it for the specified period of time, but still nothing. Any results it had were temporary and disappeared the next day. It was a waste of money

If you follow the instructions carefully and avoid coffee, dyes, etc. as much as possible, you will see results.... In ten consecutive days of use, 35 minutes each day, I saw a 4-tone improvement in my teeth (they were slightly yellow before use). In two months, I will get the replacements to repeat it!!!

Just tried it for the first time and even though I didn't expect it to actually work, I had a difference of about 1.5-2 shades, which seemed huge to me. Of course, from what I read, it said that water somehow reduces the whitening process, so right before I put the mouthpiece on, I dried my teeth with a paper towel and left the machine on for 35 minutes.

Value for money!! I saw a difference of about 3 tones, without any discomfort. What I liked is that the mouthpiece adjusts perfectly to the teeth. Just like with any whitening method, it requires avoiding coffee consumption (or at least using a straw) to maintain the white color.

I used the kit for 9 consecutive nights and my teeth are 3 to 4 shades whiter. It requires attention when making the mouthpiece as you should follow the instructions to the letter. For the price of €30, it is by far the best I have tried!

From the first 3 days, I started to see a difference and at the end of the treatment, my teeth were 3 shades whiter! It is very important to follow the instructions to the letter and be careful with coffee consumption. I recommend it for someone who wants immediate results! It's worth the money!

I applied it for 5 consecutive days for 30 minutes, the whitening was localized at that moment, after 1-2 days it was normal, at most a slight difference was shown, although it was not so noticeable... more after a cleaning you will see a difference in value for money rather than from this

The product is very reliable. After the treatment, I noticed a difference of 4 shades whiter and it didn't cause any discomfort. I highly recommend it!

For me at least, it had no result. The purchase choice was made based on the very good reviews that existed here.

Very practical the mouthpiece as it takes the shape of the teeth and the gel spreads evenly! In five days, I have seen 2-3 shades improvement in my teeth and I have a few more days left! It's worth its money!

I didn't see any difference.
"PRODUCT TELEMARKETING"

I saw a difference of 4 tones in ten days. It did not cause any discomfort. And I have kept the mouthpieces to reuse it with the replacements

The applicator is very soft and almost melted in the times that the instructions were written on it, and at the edges it folded and stuck. It deformed quite a bit, resulting in the gel not being able to spread properly and give the correct result. It should have at least another pair inside (it doesn't cost more than 0.50€) in case of incorrect adjustment!!

Reading the rest of the reviews, I decided to try it too...!!
First of all, I have to say that it took me almost half an hour to manage to adjust the mouthpiece to my teeth, with the fear of not melting it and wasting my money. One end folded and got stuck (fortunately a little) so at that point the mouthpiece does not cover any tooth!!!
As for the results, I have nothing to comment on, as it only whitens the edges of my teeth, because my teeth are not perfectly aligned!! 8 days of use and absolutely no result!!!
Even though it says made in USA, the packaging clearly reminds me of made in China...
A hassle and disappointment, especially for 40 euros!

It has 2 mouthpieces inside that are the same size and adjust to your teeth after you put them in hot water. It has detailed instructions inside the box. The gel is enough for 10 days. As others have said, it is good to leave it on for 35 minutes to see better results. I saw a 4-tone improvement in my teeth in 10 days! For the money, it's a no-brainer!

I used it for ten days and saw a difference of 5 shades. The discomfort was minimal and some white marks it left told me that it was normal due to a lack of calcium in the teeth, but they disappear in a few hours. In a few words, it's worth the money!

It does exactly what it promises! I achieved 4 shades whiter smile in just 12 days! I will definitely use it again!!
