I paid $50+ for a diffuser that was supposed to ship within 4-6 weeks. It took 8 weeks to receive after several emails to them. After only a little over a month of use, the diffuser stopped working. When I called 5minutedeals, they informed me there was a 30 day return policy... now I know why. Provided no assistance whatsoever. I will never order anything from them again! Buyer beware!
