I'm using it now for the first time. Typically I don't take anti-E's, but for business reasons I can't afford "moon face" right now.
It is definitely A+ for quality. I saw the water come off my face fast.
My only concern is it is nearly impossible to find out how many DROPS equal how much. There are a couple comments that one full pipette equals one ML... but that is almost useless info when you are trying to figure out an exact meassurement for 1/4 MG.
This weekend I'm going to meassure out 1/4 cc and 1 full CC a couple times and average the number of drops it takes to make 1/4 mg.
