I absolutely love my Pura so much that I got a second one! I have both the Pura 3 and Pura 4 and love how you can control the strength of the scent and set up the auto timer. You control it all from the app! This is a great gift idea for the home! They have a sitewide sale of 30% off and even bigger discounts on some of the holiday scents!
