“Well made and does what it says on the tin but beware, they don't work with ALL USB C sources. Mine doesn't work with my MacBook Pro but put a USB 2 to USB C adapter in the way from a USB 2 socket and it is fine (at least with my MacBook; something to do with how USB works I believe). Nevertheless, a useful little device.”
“Great little item, works perfectly as expected. I only have two minor criticisms;
1. The switch is quite firm and I find it difficult to turn on/off (although at least there is no chance of it being turned off by accident).
2. The cable on the official power adapter is white, so this on/off switch looks out of place when connected.”
