My toothbrush arrived charged and ready to use! I have used it for a little less than a week so far, and it is great. I feel the brush head is perfect for getting those hard to reach places, although it's hard to add very much toothpaste so I find myself reapplying tooth paste after brushing the bottom. I do like the timer, however the intensity of the vibrating was shocking at first. I love the fact that I can charge it and not have to worry about batteries or anything of that sort. I am glad it is easy to replace the brush heads, and I look forward to trying out different ones in the future. All in all this toothbrush has officially replaced my manual one and I look forward to using it for a while to come.
