I want to start with I'm a SAJE FANATIC!!! I have literally gotten everyone hooked on the oils and products from this company. I loved the concept of this diffuser after a long stressful day or to soothe my drive into the office in the mornings - however - the minute you put it down all the way in the cup holder - it stops working. So the only way the mist successfully rises from the diffuser if it's sitting on top of the cup holder - falling out at turns and stops. I am contemplating keeping it for my office as the connection is USB - but quite disappointed that it doesn't work for what i wanted it for. Meh.
