Review (1/5): A TOTAL WASTE!
After carefully blending my essential oils, packaging them, labeling, shrink wrapping & pricing I discovered while demonstrating the product with a tester bottle that the ball falls out & spills half the ingredients all over you. I was so embarrassed & angry that Amazon would allow a product like this to be sold on their site.
The same thing happened with the blue & brown roll on bottles also. The only thing left for me to do is WARN my customers before they buy the product that the ball will probably fall out.
This also happened to the 2 ounce blue roll on bottles. I spilled half a bottle of very expensive oils using one of these bottles. I have now ordered the metal ball roll on bottles. I'll try them out & see if they work any better.
