The built in battery wont charge any more.
After 3 weeks, the diffuser stopped working. I found out it is because out of battery. As advertised, it is solar enough, so i put it under the sun for 2 days without using it. But it is still dead. Right now, i have to manually charge the diffuser using the usb cable, which is a mess in the car. I wish i could still return it, but it has just past the 30 days return period.<br /><br />Besides that, i like the design and the smells are awesome!
