I heard massive raves about this product and seen results from a friend of mine who was using them so, I went out and purchased these.
I got a pack of 10 (5 top and 5 bottom) and after using them for two days my teeth started to get quite achy and sore, it was bearable but still rather uncomfortable.
I feel as though you would definitely need to use these for at least 10 days before seeing results as after I used them for 5 days it was only a very slight difference from when I started using them
Well this was hyped around MUO and by shaaanxo so i had to purchase it (ebay), while i do like it,maybe I'm lazy but i thought it was a bit high maintenance. But beauty is high maintenance. It definitely worked thats for sure and instantly made my teeth a little whiter after one use but it made my teeth a bit weak and sensitive. I hate waiting and i love eating so waiting for 30 minutes before i can eat was a struggle haha. The only thing is you have to constantly use this to keep up with the white teeth or else they will go back to their normal colour again. I did read somewhere that whitening teeth really does break down your enamel which makes your teeth weaker. Ive avoided this since then but i will probably still use this the night before a special occasion or something.
