Very soft to the point that no matter how much you brush your teeth, they don't get clean.
I was not satisfied with this purchase despite the many positive reviews I saw here.
I would only recommend it to someone who has a lot of sensitivity in their gums, but in terms of teeth cleaning... not really.
In the end, I have ended up using it to clean transparent cases, there it might be useful for you.

It is indeed very soft, I don't think I have ever had such a feeling from another toothbrush. It will not hurt your gums and it also comes with a free floss. It is worth its money

It didn't suit me. Personal opinion completely. It is soft, it simply has a tragically small surface area, that's why I gave it one star.

By far the best toothbrush that exists. Very soft and with an amazing dense composition of bristles.
The best for gums!!! Must buy!!

I bought the aforementioned toothbrush after reading the good reviews from here. Initially, the toothbrush doesn't seem like the ones from the Super Market that we have all been using for so many years. It is quite flexible, reaches deep, and seems to clean the teeth quite well since its bristles are extremely thin.

The only question mark for now is a slight pain in the gums, but it may be due to the time the gums need to get used to it.

Gentle on the gums, cleans the teeth incredibly well. The entire clinic range has nothing to do with the toothbrushes from the supermarket. One of the best toothbrushes I have ever used. A plus is that it also includes 5m dental floss as a gift.

Simply the best toothbrush I've ever had.

PERFECT

It is very soft, maybe even softer than the 15/100. It is perfect for cases with gum sensitivity or after cleanings. For general use, I think the 20/100 is the best choice.

You won't find such a good toothbrush at such a good price anywhere. Personally, I used branded companies from supermarkets and none of them did the job, until I developed gingivitis and plaque due to a bad toothbrush.

This toothbrush is so gentle that it makes you wonder if it cleans your teeth. And yet it cleans them without you even realizing it. If you compare it to a supermarket one, you will see that it has triple and quadruple the number of bristles. It is very lightweight and very user-friendly. Personally, it left me speechless, it did an amazing job in my mouth. I recommend it!

Very good toothbrush with soft bristles and rounded edges that will not cause damage to the gums even if you brush with force. I had also bought the Elgydium Clinic 15/100 which I used before this one and I consider it slightly better than the total black, I think the clinic cleans a little better!

Very soft toothbrush that fully respects the gums and at the same time cleans perfectly.

Also, on its packaging it states that it can be sterilized in the microwave oven in a glass of water for 1 minute at 600 W. Something that I have not encountered in any other toothbrush and I consider it quite useful.

The best toothbrush I have ever used. It cleans the teeth very well and is very soft so as not to hurt the gums. It also includes a 5m dental floss as a gift, for maximum cleanliness between the teeth.

Unbelievable toothbrush.. By far better than the ones you find in supermarkets.. It caresses the teeth and cleans perfectly!!!
