The roller seems to work pretty well, but they do leak a little bit sometimes, so make sure you don't just throw it in your purse or set it down on something without making sure you have wiped off any excess.  Essential oils leaking out can definitely do some damage to painted surfaces..There are other information for this review, one is This reviewer did not purchase it and the other is 0 people think this review is helpful.
