I bought this a few weeks ago, and it seems to be a very good toothbrush which my 9 year old son likes to use. However, I can't find replacement brush heads -- which means my daughter can't use the toothbrush (the original package only comes with one). I'm very frustrated, having several times brought home replacement heads I thought would work, only to open the package and not be able to fit them on. Then back to the store to return them, only to see that there aren't any replacement heads. It's amazing to me that they sell the brush, and then next to it on the self are only the WRONG replacement brush heads!!! I cannot recommend this for this reason!
