I purchased 3 packages of rollers for my oils. They will only replace 2 of the packages since one of the packages was purchased 1 year ago. I understand it has been 1 year, but all 3 of the packages have the same issue. They are all too large to fit on any of the oil bottles. This shows the company is neglecting quality control. It makes you wonder what other quality issues are going on with their other products. This is bad news for Young Living.
