Upon first purchasing this item, I thought it would be perfect. I got it for the office I work at for multiple of us to share. It was great for the first three days... Then, out of no where it was impossible for me to open. Which is when i noticed a crack in the clear portion of the defuser. I was slightly disappointed as we had only run the defuser three times, and was expecting it to last a little longer. I also noticed when I finally got it open, that there was an insane amount of build up inside of the defuser. I used some hot water and soaked it and was able to get all of the build up off. Which is what I thought was causing it to be hard to open... I ran the defuser as normal that day, and the next morning, I went to open it, and again, i could not open it. I then noticed that the clear part was no longer attached to the rest of the defuser, and the build up was even worse then the day before.
I knew going into getting a cheaper defuser that it wouldn't last very long, and we only needed it for a short period of time... but i wasn't expecting the short period of time to be less then a week after purchasing it.
