I ordered it several times. Although there is no big problem in use, there is a case that a bag of small black fragments is lacking corner of ferrite. Ferrite is prone to chipping, so I would like you to take more care in packaging.

The plastic of the matching part was quite thin, and one piece had already been cut at the time of delivery. Even if one was also adjusted, it was fixed so it was used as it was, but it is necessary to be careful.
The largest size is used for FM radio antenna line. Although it is not perfect, even in a room with poor reception conditions the radio wave has improved considerably. When the antenna wire is looped and grasped by hand (human body can also cut noise like a ferrite) in a house with many noisy environments such as personal computer, wireless LAN, AC adapter etc., the radio wave state is clearly improved In such a situation, I think that it can be surely expected to be effective.
