I've been using Sankyo Chemistry buff a long time before, but this time, I bought it because it was interesting. Purchased a # 5743 cushion pad sold separately. The feeling I tried is because the hair feet are rather short, there is a sharp point. I think whether durability is the same as that of Sankyo. (I felt it was harder for hair to escape than Sankyo's item.) Initial investment will be higher than that of Sankyo (cushion pad is sold separately, it is quite expensive), because the cushion pad will not get in early, buy only the buff pad It is an advantage to finish cheap next time. Also, it is convenient to wash the buff pad only when washing the buff. For the cushion pad integrated type, the cushion pad sucked in water, it is quite hard to drain water that has sucked. Because you can wash only the fluffy buff pad, draining can be done easily by merely lightly squeezing the buff pad so it's really easy. Experience up to now, since the cushion pad did not become useless before buff became useless, I think whether cost performance is good in the long run. (There seems to be durability only to use 10 buffers) But the size of the buff pad is larger than the cushion pad, the buff is popping out from the cushion by about 5 mm, and the jumped part has no hardness at all . For that reason, I want to polish by using the edge near a mall or a small place, it is a point of dissatisfaction that the margin is out of the way and it can not be done. Can not improve only that part.
