I first bought one of the Spider-Man toothbrushes for my son who is 4 because we were shopping and he HAD to have it. I was a little skeptical because it was kind of pricey for a tooth brush, until we got home. My son had to KEEP brushing his teeth. He LOVES it and loves the lights that tell him when to go (green), almost done (yellow), and done (red light). Of course my youngest who saw how neat this toothbrush was and that it lit up, he had to have a similar one. The following day I went out and got him one. All in all its a good tool to get children to brush their teeth and a good way to get them to time how long they brush their teeth (should be 2 minutes but the lights go for 1). Also, the batteries last a long time in them which is another bonus
