Review on RND Dock for Samsung Galaxy S4, S4 Active, S6, S6 Edge, S6 Edge Plus, S7, S7 Edge - White/Purple Docking Station with Dock Mode Cable and 2.1A Charger (Compatible with Most Cases, Including Rugged Ones) by Eric Edgar

Its functionality, workmanship is not very good. The retractable sleeve for the thicker case is flimsy/thin and difficult to remove/reinsert. The docking app that should be invoked when docking the S4 with the thick charging cable and the included charger does not work. Charger, it does the job and I can charge any phone that uses micro USB, it docks to a flat phone without having to remove the case. The USB port also doesn't dock the phone smoothly and is a little tight. For these reasons, I simply wouldn't buy anything else. I would probably be willing to pay $10 or $12, but no more.
