I’ve had my diffuser a fews now & I love it!  It did cost more than I normally spend on a diffuser but I’m so glad I made the leap.  I can’t figure out how they made a rechargeable unit that lasts all day, as all the other ones out there only last 2-3 hours before needing a charge.  It has a large basin so you’re not having to refill during the day.  And the icing on the cake is that it’s absolutely beautiful!  The cover is thick glass, when most others are plastic.  I can’t say enough great things about this awesome diffuser.  My only regret is that I wish I had bought it years ago.
