This toothbrush comes with the main unit, 4 brush heads (all the same), and a charger. It has 6 modes - sensitive, mild, cleaning, brightening, polish, and massage. Each mode vibrates at a different frequency respective to it's use.
The whole unit is very light. The bristles are soft. I think this is good option for older children, and is a good value considering you get 3 extra replacement heads and it's rechargeable.
Ive tried a few different brands similar to this product, and I would like to see this brand have an easier to read mode menu. It's pretty dark. I would also appreciate different types of bristles (soft and hard). I will be using for my 11 year old, and will update on how long the charge holds.
