Unfortunately...this was not a good buy

I was really excited to test this out, but unfortunately it did not work as I expected. It was easy enough to set up and get going, but no matter how much essential oil I put in with the water I could not get the aroma to come through. I literally ended up wasting about a half a bottle  of my favorite oil because I really wanted this to work. I even cleaned it out and tried again with a different oil in case the one I was using was not potent enough and I was still shocked at the lack of aroma I was getting. I even got down to where the vapor was coming out and I still didn't smell any. I am not sure why mine does not work or if I got a dud, but I was pretty disappointed. I really wanted this to work as I am a big fan of aromatherapy, but unfortunately this did not work for me.
