The device is too big and the fact that it has to be plug in while being used takes up too much space in my car. The cord always gets tangled in something
While this might be a good concept the fact that it needs to be continuously plugged in to a car USB makes this a no for me. The original beta test didn't really explain this up front so I made a bad assumption. I will continue to test as I promised to do, I wouldn't purchase this in the future. Also by requiring the USB and no battery a number of cars won't be able to use this.
I love having pura scents in my car! The only drawback I see so far is that it has to be plugged in at all times in order to turn on. I thought it was going to just need to charge and then I could place it anywhere in the car. In reality, it needs a place to be plugged in, and then there are cords all over the place that get in the way.
