It is okay.
This product is handy and cute. My skin feels warm after I roll this product on my skin. I have not found any difference since I used it for 3-4 weeks. I had some difficulties to use it at the beginning until I watched the instruction from YouTube. The booklet has not had enough information. I do not have much time so I only massage my face at night for 5 minutes. I do not use it to clean my skin because the machine gets dirty easily and hard to control as well by covering a cotton pad on top. Be careful, it can not be used under the water. I bought this item after I saw all good comments on this product, It can help improve you circulation some how, but it may take long time to see.
