I originally bought this to connect a mouse and keyboard to my KVM switch. On a positive note, the workmanship of the cables and end connectors seems very solid (only a few months of use), the cables are flexible, very light and travel-friendly with plug-in connection, everything works fine, but there are frequent jumps that cause keypress lag . or press and hold a specific key for a second or two. Ultimately it's too annoying to mess with and I replaced it with a powered hub and haven't had any issues since. I haven't tried any ways to charge the device or transfer data, so I can't comment on that.
