The best toothbrush I have ever used! My gums don't bleed, it cleans my teeth thoroughly, the bristles don't easily break, and it doesn't cause gagging.

The 25/100 is hard and after trying the 20/100, I found it more convenient. It is like average compared to the others

I have been using it for years. It comes in soft, medium, and hard, and due to its small head, it does not cause nausea during brushing.

I am very satisfied. The bristles do not break, like in supermarket toothbrushes. They easily penetrate between the teeth. I bought the same for my son and he was also satisfied.

Not ergonomic design, hard to reach back molars and doesn't have a good grip in the hand.
The bristle rows are minimal, so more movements are needed for certain areas.
The 25/100 is a medium to hard brush, prefer a softer one.
The edges of the bristles are indeed well-crafted and give the impression that no matter how hard you try, it's difficult to irritate the gums.

By far one of the best in its category. Ergonomic handle, excellent quality bristles, perfect size. In my personal opinion, it leaves an unbeatable feeling of cleanliness. Also, I have never had any injuries or irritation of the gums.

By far the best. My gums used to bleed, but since my dentist recommended it to me, they no longer bleed.
