It breaks down very quickly. So how many are needed for a month? It doesn't say how long each one should last

The only thing that makes it difficult for me is that the wire is very soft and bends easily. For the back teeth, it takes a bit of skill to get it through because of the wire.

Completely unsuitable. I bought them in my attempt to find reliable ones after the tepe ones which broke and snapped in less than a day's use, but these are even worse. They may not break the wire but they bend so much that they are completely unsuitable. I won't even comment that after a little use you will have fibers from the brush stuck between your teeth. They shed worse than an Angora cat.

I was using Tepe, but they weren't as convenient. These ones were recommended to me by a dentist and they are easier to hold in your hand to clean your teeth. Also, the brush it has lasts for more uses than Tepe.

I have already bought them three times. They often need to be changed, but it's okay, one package has four, so it lasts for two or three months if you're careful not to constantly break them. It helps to fit between the teeth when there is no space. My dentist recommended them to me to use with a stabilizing bar between the teeth after orthodontic treatment

Stay away from Elgydium Clinic Mono Compact Interdental Brushes 0.7mm Red. In the new packaging of 1+1 gift with black color on the top of the brush, it is avoided with certainty!! (The old ones are very good).

Very poor quality wire, it bends with the slightest touch, resulting in it not penetrating but bending before entering the middle of the tooth. You can use them with great difficulty once and then they are for disposal.

You can easily injure yourself. No comparison to the previous models without the black shade on the top. Unacceptable quality. Get the old ones, I will provide a photo.

One should be careful with the brushes to choose the appropriate one. These specific ones are only suitable for very small to non-existent interdental spaces.

It is very soft and breaks after one use. Of course, it may be due to my tight teeth alignment, but I would not buy it again because, as I mentioned before, it breaks. I preferred the blue ones and wherever the dental floss gap is smaller.
