Review: Pleasantly Surprized - Upon opening the package I was surprised to see the diffuser. I thought it was just an ordinary size unit. This diffuser is big, beautiful and I absolutely love it. I am feeling so happy for making this choice. I set it up and boom! It's even more surprising how well it works. The mists are large and for the first time I really get the true aroma of my rosemary essential oil. The small diffuser I had did not do justice to my essential oil. It is day one and I am enjoying this HealtSmart diffuser so much as already. The room is so nicely fragranced with the rosemary oil. The unit is well made and the water tank lid latch a bit which I appreciate. My other diffuser that was always spilling water. I truly hope this unit will be long lasting. It carries a manufacturer 1 year warranty too.
