As with all Sound Devices accessories it is _expensive_! But, I needed it since I don't have a laptop with USB-C. It does what it's supposed to. The workmanship is not great, though. It feels a bit clumsily made and the USB-C connector wiggles a somewhat. (The protruding bit is not firmly set into the cast rubber/plastic.) Also, the USB-C connector housing "bottoms out" before the connector which makes it difficult to know whether it is properly set in the device. So far I haven't had any problems, but who knows what will happen after it wears a bit.
