actually i kind of like it [SEP] i do not know what made me buy this but somehow i came across it and was curious to try one i just finished my first stick which lasted over a week every day i would chop off the part i used it probably lasted about days you might be able to use the same part multiple times i just did not want to i actually noticed it somehow whitened my teeth the taste isnt good but i got used to it after days i still used a normal toothbrush as well but i was curious to try thisi would not replace my normal electric toothbrush toothpaste flossing for just this but i use this along with the resti might buy another pack when this one is gone but more should last me a few months
