Review on Essential Teenitor Reducers Transfer Droppers by Andrea Olson

I bought these to make small batches of essential oil blends. There are many recipes in our book that recommend mixing before diluting in baths, carrier oils or diffusers. It's perfect and holds about 40 drops of oil. The small hole in the opening reducer makes it difficult to dispense drops, but from what I've read in reviews of this and other small mixing bottles, that's just the nature of the beast. Turn it upside down and tap or use the included glass dropper to get what you need. I haven't had any issues with breaking bottles installing the via, but I suspect the ones that break don't apply. Even pressure on the plug when plugging in. I would recommend using an essential oil bottle wrench (I have one with a set of roller bottles) or at least making sure the hole reducer stays level when inserted.
