Do not do business with Amiro. They expect you to pay for return shipping on their defective product.
I was sent a defective R-1 Pro device which wouldn't hold a charge for more than 15 seconds. I contacted Amiro service and was emailed saying I had to take a video of myself using the device to make sure I was using properly (like I can't read instructions). I did as requested and received an email with return address but I'm responsible for return shipping!!!! Horrible customer service, so I have to pay expensive return shipping and hope for a refund. They are based in China so it takes days to hear back from them. Only buy products from U.S. Lesson learned and other posters are correct, these beauty influencers receive devices for free for their positive reviews.
