Originally I was going to give this review 5 stars because the bottles seem so high quality with the glass and the nice labels. But now that I've tried to use one, this is what happened: the first time I filled it up with my essential oil blend and sprayed it, it worked perfectly (another reason for potential 5 star review). But the second time I filled it up with the same essential oil blend, the spray pump no longer seems to be working. The liquid still comes out of the spray pump but it comes out in huge drops as though it were dripping from a sink. It seems as though there are two holes in the pump: one hole shoots out a tiny jet of spray but the other is dripping the immense drips onto my hand and onto the floor whenever I spray the bottle. As a result, most of the oils are being wasted by simply running down the bottle and onto the ground. :( I'm really disappointed because there are 6 of the bottles in the case!
