Oral-B is our toothbrush brand and we have been using them for many years and they haven't had any issues!
That's why I chose the same toothbrush in the children's version for my little one (4 years old).
It has 2 speeds, but I only use the first one.
There is no indication when the battery is running out, but I believe we will learn when it runs out through its use.

The 5.5-year-old child accepted it pleasantly and enjoys brushing their teeth. The 3.5-year-old child struggles a little as they feel it is a bit big for their mouth. Nevertheless, it still does a good job. And the battery lasts at least 4 times.

I give it a low rating because it doesn't have a battery indicator, so you don't know how much battery life is left. With the same amount of money, there are better options

The little one went crazy with Elsa. Hoping she learns to brush her teeth on her own. The battery lasts 4 to 5 days morning and night after 2 months. Be careful with the replacement because due to moisture, these toothbrushes easily get black mold. It needs ventilation and good drying.

I have 3 electric toothbrushes, 2 of which are the classic ones for adults and one is specifically for children. I have had the 2 adult ones for 3 years, while the children's one for 6 months. Unfortunately, the children's one is made of a material that attracts mold. Although all 3 are rinsed and not dried before being placed in their case, the 2 old ones have not been affected, but the children's one has developed mold (on the handle) that cannot be removed at all, because the handle has indentations and holes where the mold has accumulated.

I could write a lot, but I will simply say that if you have an electric toothbrush as an adult, get one for your child from the age of 5-6 and onwards

There is no indication for the battery status, so you have to run out of battery to realize it.

Very good toothbrush, especially for its price. Even my little daughter, who just turned 3, loved it. They brush their teeth on their own and have fun doing it.

It cleans very well. No comparison with the manual one. Also, a child can easily handle it.

It is the best in its category. It takes spare parts for children and adults. It has two speeds. It has fallen down 500 times and has not suffered anything. Nice design. What else does a toothbrush need?

For the quality of Braun & Oral-B, I won't say much, its quality is well-known. My 6-year-old daughter is thrilled with it, she now goes and brushes her teeth on her own without us reminding her. It has a small brush and some stickers that stick on top of the toothbrush. It also has a travel case. It's worth its money.
