Not enough power to connect USBs, had to return and get a different one. Pretty useless.

Bought it for output to dual monitors. Monitors would not recognise two HDMI outputs. It only worked with a VGA output on a monitor and HDMI on the other. After 4 weeks, it only works with a single monitor (only VGA via a USB and an additional converter). No HDMI signal (tried two cables).

So far so good (had it for a couple of weeks), bought it mainly so I can enable dual screens and it works a treat.

Unfortunately the product did not work for my laptops, trying to share 2 monitors with different resolutions
