I don't understand why there are so many different types of toothbrush there. I only got this one to try because I got a promotion from SDM. I don't feel there's any difference with other toothbrush. it does the job of cleaning my teeth. the bristols are arranged differently

it's definitely more expensive than a regular colgate toothbrush

For me I found that this toothbrush was too soft, and I went to a different one
