The bottles are strange. I couldn't get the product to come out of any of the bottles no matter how many times I pumped. I opened all three bottle to find that there isn't a tube inside that draws the product up and out when you press the pump top like similar bottles. I thought it was a manufacturing error and wanted to return the product. I called customer service and I was told that you have to turn the bottle upside down and tap it to get the product to flow. I store them upside down and have not had a problem since. It's too early for me to comment on the effectiveness of the product but I wanted to let everyone know about the odd design. I'm sure it wastes less product but it would have been nice to read about the different design and how to use/store the bottles.
