Do not buy!
I bought 4 of these for Christmas presents because they came in fun colors.  Within 1 month of use, 3 of the 4 brushes had started to crack from the bottom up in the area where the charger goes.  After 3 months, 1 of the three died completely and would not recharge.  I attempted to get in contact with the company to get the replacement offered in the warranty, but that was impossible without setting up an account on some weird third party website.  I hate that I wasted the money on these toothbrushes, but it is not worth the time to try and figure out how to get a replacement at this point.
