Review on True Essence Amber Bottles Roller by Amanda Davis

Too small for the oil metering, buy a larger size. The ball is so small that it hardly rolls. At first I thought the first one I grabbed was defective, but then I realized they all are like that. Then friends advised me to take one size bigger. 3ML is still quite small. My 10ml seemed to be too big (but works great) so I'm waiting for my 5ml to arrive. Sure, the smaller ones will fit in your pocket, but be prepared to roll, roll, roll, roll, roll, and roll to get it all.
