Got the luxe package after 2 weeks. Comes with introductions in english and chinese. This is not the package that mentioned in the picture but i don't care i believe that them all have the same influence. Also my friend recommended me this and he used another type of this Crests. So i used it already 11 times. Which means it just half of package and the result ia amazing! I put them every day for 40-50 minutes. I skipped 2 days beacuse i was busy but its ok.So what is in the pictures its just a half result and im still speechless of how worth this is. There is a little bit sensitivity but its so worth it!! Thank you. You surly buy again.Have used for several years. Excellent resultsSo once I was hiking and I fell and broke out one of my teeth (gross right). Well I have struggled with camouflaging it because of the fact that it was my front teeth. After this incident, I was very insecure about my teeth, as they grew far yellow-er than my fake tooth. I purchased this product in hopes of re-matching the teeth, and, with only less than a week to go, my teeth are great! They are all the same color, not to mention that I've never gotten so many compliments before until now! (great smile, white teeth!) Buying this product on here was the best decision overall, because of the fact that it shipped-fast, was exactly as described, AND nearly half off the price of the product in the drug stores. GREAT DEAL!!!!!It does not work as well as advertised (of course) but it still does a relatively good job for the price. However I did not take 1 each day for a month like they say you should, I spread it out as I needed it (teeth where pretty white to begin with however I bought these as a last minute kinda thing)Easy to use .....I drink coffee daily and smoke so this really made a difference. My teeth could still be whighter but my teeth didnt get all sensitive from it.Tried it and it works. The only drawback was that my teeth became sensitive to it during the last 3 applications. Apparently, that's a common complaint among users.I was skeptical to try this out because I know some people that have tried products like this and were not too satisfied....However, I didn't have the $300 plus to spend on professional teeth whitening so I thought, hey I'll spend $30 and try it out....Well to my surprise it worked beautifully! My teeth were verrrrry stained yellow and now they are beautifully pearly white....Not neon white, but at least 5 shades whiter and I'm still not done...I have about 7 strips to go....So happy I tried this out, I am definitely gonna do this again in 6 months....great product.Works great keeps whiteness if used 2-3 times a weekMelhor maneira de clarear os dentesOdiei o produto e achava que vinha com o laser. Muito ruim.great price fast delivery. a+ seller thank you
