My experience was not a good one, so i don't have any real pros to mention. Cons however, are: Scars and lumps that wont go away.
The results were not that great. Soarness lasted a pretty long time - at least mine did! Compression garments have to be worn for a while, so depending on what your having done, you have to wear clothes that will hide the garment underneath!
Wish i would have saved my money. I won't be doing this again.
