It works well, and allows the built-in DEX (Desktop EXperience) in the latest Samsung mobiles to convert the phone to an Android desktop. This works as advertised as well, although it takes some getting used to using Android apps instead of Windows, OSX or Linux, to be honest. Great if you were stuck in a motel room without a laptop, and needed a computer "fix" or just wanted to do some emails or even work on a project (using the various apps on your phone). Niche market, perhaps, but works well with a USB keyboard and/or mouse. Recommended.
