I was looking forward to using this in my diffuser. Unfortunately and despite shaking, no drops were released from the bottle. Spoke with staff at store who tried very hard to be helpful. I was informed that the product is thick and to use a pin to enlarge hole in the stopper. This did not resolve the problem. Still have not been able to access any of the product as of today. I am wondering why this type of bottle would be used for a product with such a high viscosity.
