I wouldn't touch Karma with a 1,000 foot pole if I were you. They lie to customers and change terms and limits on existing customers. I, and many others, returned our devices nearly a year ago and have still not received refunds. The company's response when pressed for updates on refunds seems to be "shrug, we'll do it when we do it."
