I have no idea what the warm review means as I write this. It's solid and durable. It comes with a fairly large booklet detailing how to use it with smart devices. It seems that to transfer photos you need a file installed on the device, it sounds complicated. I bought it to use between devices with USB-a and USB-c ports, but the device transfer is a bonus. I ordered one for my daughter as her iPhone fills up quickly with iMessage photos. She likes it very much. There are a few things that could be improved. There is absolutely no grip to take off the longer cap. My fingers just slide over the smooth curved metal instead of removing the cap. That. Also, the longer USB-A connector is easily lost. I figured from the photo that the cap would somehow be attached to the other end of the device or connected by a chain so it wouldn't get lost. If instead it comes loose and needs to be installed somewhere, it can easily be lost or forgotten.
