Works effectively on cupping different parts of the body.
This cupping set is great to use for the back.  The different cup sizes woks for different parts of the body.  The small ones I use on the neck part. The medium sizes I use on the  middle part of the back and the large ones I use on the lower back. I wish the hose is longer.  Also be careful of  dropping it on hard surface as it can crack.
