Was great until it stopped working
Color: Pink
Got this toothbrush for my daughter back in February. It worked amazing. The battery life was great, timer was great, and no complaints. From February to August it worked without flaw then the toothbrush would not longer turn on. Initially we thought it just needed to be charged, and even felt my daughter was not charging it properly or not long enough, but it never turned back on. The red power light will turn on, but the vibrating never starts. After several attempts at charging I reached out to the company 2x via email after reading another review of them replacing the toothbrush but have still not received any response. The company did not even send an email acknowledging they received my email. I guess you get what you pay for. I wouldn't recommend buying. Now having to buy another toothbrush, I should have just spent the money initially on a brand name toothbrush rather then now spending twice the amount.

After writing this review, I did get a response from the seller who agreed to replace the tooth brush. I was also offered a refund, which I appreciate, but definitely was not expecting. I truly just wanted a replacement. Great customer service response following my post.

Color: Blue, Color: Blue
This toothbrush is perfect for kids! The cute dinosaur design makes brushing exciting, and the soft brush head is gentle on little teeth and gums. It has different cleaning modes, which is a great feature, and the timer helps encourage longer brushing habits. Easy to use, lightweight, and a great way to make dental care fun every day. Highly recommended for children!
