Elegant and looks great on granite!
I really like this diffuser.  It is glass on the outside with a plastic interior.  It is very easy to use, plug and play.  You place the water and the oil in the some container.  I used filtered tap water and did not have any issues.  It puts out a decent plume of mist, but there have been no issues with any condensation or oil residue.  I am very new to the diffuser scene and was very concerned about placing it on my wood or granite.  I started by placing it on an older table and about every hour moved it to a new surface.  I placed a paper towel below and there was no moisture at all.  The top of the diffuser just sets on the base, it does not lock.  It makes it really easy to refill, but you would need to be careful in higher traffic areas.  The whole diffuser sits on three tabs at the bottom that easily allows the cord to come out and stabilizes the egg-shaped design.  I've refilled it and moved it several times and there has been no fingerprints or smudging on the glass.<br /><br />It came with an instruction manual and a small cup to refill it with water.  The max fill line is a bit difficult to see.  Mine ran for 4 hours without having to refill.  There are only two modes: constant mist or intervals of 30 seconds on and 30 seconds off.  I would definitely recommend purchasing this diffuser.  It is a bit pricier than some of the other diffusers that you can purchase, but it very attractive and looks amazing on my granite.  If you are looking for a reasonably priced diffuser that is not plastic and does not have all the lighting features, this diffuser is for you.  This is very high quality and very nice thick glass.<br /><br />I did receive this product at a discounted price for my honest and unbiased feedback. I strongly rely on product reviews when making online purchases, so I attempt to give a thorough and accurate description about my experience and the product when writing any review.
