Constant transfer rate of 42 Mbps when simultaneously copying two 30+ GB video files from two cards (MicroSD and SD, both Class 10 U3 V30) to the desktop. I also tested it on my phone (Samsung S9) and both maps showed without any problems. It's super light. So much so that I was worried at first, thinking it wasn't going to work well. I'm glad I was wrong. The device is a bit chunky compared to other similar products. For my use it doesn't matter. Overall I think this is a great product.
