[This review was collected as part of a promotion.] My kids 7 and 8 are very excited to use this. The color changes after about 30 seconds of robust brushing. They liked the taste also. The top is a bit messy. But, I chalk it up to kids being rough pushing the toothpaste out. Still recommend for a fun goal to have in the morning.

[This review was collected as part of a promotion.] We were excited about this because my son has a hard time brushing for the entire 2 minutes. The first time he used this he said he couldn’t tell when it changed colors, that it looked pink the entire time he was brushing. The next time he said he kept spitting while he was brushing holding that would help him decipher the colors and it was always pink. He doesn’t mind the taste, but the color changing feature doesn’t seem to work.
