Review (3/5): Roller doesn't spin all the way around, no directions.
No directions or "quick start" to get you started with Gua Sha, so expect to google/buy a separate book.
The quality of the Rose Quartz is nice and has good color, but the construction of the eye roller is a bit janky. The smaller roller on mine doesn't spin fully around, it gets caught and you have to switch directions, so it's annoying to use. Seems like they don't have good QC for the product checking each roller after manufacture.
