Just to add to the conversation... I don't mix for others, this is all purely for my own use. All I truly care about is consistency of the flavor of my mix, and the ease of making and cleaning up. All 3 of which were more than worth the $95 investment.
One of the problems that led me to mixing this way were the multitude of ways that my flavors showed up. i.e. many different styles of dropper tips, sometimes even different between the same supplier in the same order, or no tips at all. None of it matters as all I have to care about is did I meet the weight of the item I am adding.
