We are restocking the Now Bamboo Diffuser at the request of our customers. It just looks better and is made of real bamboo and not plastic. It is easy to use, BPA-free, quiet, runs longer than most, is easy to clean, runs for 7 hours on the continuous setting and up to 14 hours on intermittent, and is attractive to look at. This diffuser does not use heat, thus preserving the integrity of the oils. It can light up and rotate through the color spectrum, can stay on one color, or you can turn off the light feature. It holds about 5 ounces of water. Another nice feature is that it does not require distilled water.
