Had a hard time deciding between the jade and rose quartz, but started with this set since I wanted the ridged roller. I love that instructions are included, the rollers seem to be strong, silent and not squeaky, and the foam packing inside the box protected all the pieces during shipping. I really want to get the jade and amethyst just because so they are so pretty!Plus, this set arrived while I am in the middle of a cold/flu. My face is all puffy and sore from all the coughing and sneezing and nose blowing. I followed the instructions for both the roller and the guasha tool, and even used them down on my neck and shoulders a bit. My face feels so much better and the sinus pressure is a lot less too. Don't know if it will help me get better faster bc of the lymph drainage, but hey, can't hurt, might help and I feel better! Really recommend this set.
