Review (4/5): over all great! but..
like many people, my product came broken, but it wasnt actually broken, if your roller comes and one of the jade pieces are popped out of place, all you need to do is bend the metal pieces that pinches it in place just enough to put the jade part back in the hole or holes then boom! its fixed. while that was underwhelming to see, the over all product is great, comes in a cute sleek box and packed nicely, i have no idea how the rollers pop out of place like that during shipping, but i hope in the future its fixed. note: if you buy this product even the care sheet says that the roller popping out of place isnt a big deal and the product isnt broken.
