I bought three items of different size (diameter). It is a nice feeling such as the hardness of the brush. It is very convenient to be able to purchase brush parts and handle parts separately.
It is saved if there is a slightly smaller size than the small size of the 1st system.
I bought it in November and started using it, but at the end of January my hair has come out and I can not use it anymore. The other Vancan cleaners have been using it for about a year, but because it is thick, it was really expensive, it was totally bad. Was it a defective item?
