I have to admit that I still had some doubts about this, if it goes again same as always in the past. 1teethwhitening promised for all of their products 100% money-back guarantee, so I had nothing to lose. I dealt with my teeth about 10 times and already after the second time I noticed some whitening in my teeth!
Kuid 1teethwhitening.com kõikidel toodetel on 100% raha-tagasi garantii, seega polnud mul midagi kaotada.
