I have been using this hydrator for four months and I am pleased with it's performance. I love the clean cooling effect of the vaporizer. Once you develop the technique this is a lovely attachment. I like the large base on this model as it is easy to set down and the stability of the base is nice. I broke mine, my fault, and when I called VB's took great care of me. It only took two days to get then new one in hand. Cleans easily with alcohol.
