Review title is Spray heads stop spraying. [SEP] Nope. These stop spraying after a few days. I made room and pillow mists for gifts. I'm glad I tested them first! I emailed the seller and they told me that if my essential oil mixture is too thick, the spray heads will get clogged. My mixture was not thick, but I watered it down anyway, and cleaned the spray heads very well. It still didn't work. I'm giving it 2 stars because the customer service was very good. They sent me a few new spray heads at no charge...but the same problem keeps happening. I really like the bottles though, and use them for my homemade reed diffusers. Even though they are supposed to be used for essential oils, I wouldn't recommend it. I switched to bottles with a trigger sprayer, and they work much better.
