toothbrush I bought with my own money

The oral care product I bought with my own money is the Atomy toothbrush.

I prefer toothbrushes with soft bristles and a small head, so I found this product quite good to use. They say it is better to replace toothbrushes frequently rather than focusing on the price, so I think the best approach is to use a reasonably priced toothbrush and change it periodically.
