Purchased so I wouldn't be using my work laptop at home for small personal items via Chrome. I didn't need to buy a brand new computer so I opted for this instead of paying for an OE docking station for Dex on Samsung. Connects easily and has the right interfaces to turn your Samsung phone into a dedicated computer. The monitor must have an HDMI connection. There are only requests for improvement if you have two USBs, if you have a keyboard and mouse on different USB dongles. With just one, you should have or get a keyboard and mouse that work with the same dongle. An SD card is handy for transferring photos from your DSLR to your phone without having to save, email, and re-download them to your phone. All in all a great product, a small one that doesn't take up space on your desk.
