Pros: Using to get HDMI (video output) port from a newer Chromebook, to use a larger display monitor. Was not sure that the video would be available from the Chromebook's USB-C port until I had this device. Just plugged it in and set Chromebook to mirror the screen. Other setting also worked.

Cons: Was working OK, but then became intermittent. Beyond NewEgg warranty and can not yet find supplier for their warranty. Have ordered another one as a replacement.

Overall Review: Would recommend for supported computers that do not have an HDMI port, for use with display monitor having only an HDMI input. Perfect for my application and at a reasonable price.

Pros: Appears to be well built, sturdy. Nice to have all the USB ports and power. A Little heavy, but the weight helps to keep it in place on flat surface.

Overall Review: Purchased three and would buy again if I need more.

Pros: Nice product. Has light to indicate that it is powered (from computer). Using it to get up to four USB-3 ports from the one on my laptop. Presently using for wireless mouse and added memory.

Overall Review: Would recommend to someone needing to expand their USB-3 port to more external devices.

Service and reporting on delivery was good, but there was a weather related delay. Seller responded to my inquiries in a timely manner. This refurbished unit looked like new (manufactured six month prior to my receipt), and came with original parts in original box. There was no instruction manual with the unit.
