In addition to the brand, there are personal factors in using such products. It is useful to some people but not necessarily suitable for them, so I personally suggest not buying it. Of course, I said it from my point of view. If you still want to buy it, I personally suggest that you must choose a good brand.
I bought it from McCawlin. Because of work, I usually wear it at home. I'll wear it as soon as I get home. I usually do calf massage. I don't know why, but I don't feel particularly thin. I think it's either because my method is wrong, or because my time is too short to work ... usually massage feels good, hehe.
This product may not suit me. You can reconsider.
Sorry, I forgot the exact amount. The freight is below 100.
