Review on StayGo USBC Travel: Twelve South's Ultimate Solution for Portable USB-C Connectivity by Chase Arellano

So far so good. Everything works fine but I've seen others doubt SD and MMC and I've tried both and both don't recognize formatted media!?!? So far this works fine on my MacBook Pro 16 (2019). I will try HDMI and Ethernet soon. Two lengths of USB-C cable is just what I needed, especially when I put the laptop on a stand (other USB-C hubs hang in midair and pose a hazard). Updated: On a 2019 MacBook Air, this drains the battery!?!?!?! Only 30W are consumed. I tried this with power connected to StayGo and no other ports were used. HM? I have tried this several times. Same result. unusable.
