Bought 2 items, and was very excited to try both (1 helo, and 1 melo). Neither worked when I opened the packages, I reached out to customer support, and they asked me to send in a video. Unfortunately the file size was too large to be emailed so I asked if there was another way to send it. I even offered to return the product before the video was ever displayed so they could see both devices were defective. I never heard back from them. After seeing the great reviews on tiktok, I thought I would try them, I just wish I didn't waste $30 plus the 'insurance' against damage, as it didn't seem to matter.
