I bought the Ownboard C1 with the Samsung battery's. I've had it for about a month now and everything's still working great. I have no complaints. It's lots of fun to ride, charges quickly, climbs up hills, the brakes work great, the remote is super comfortable in the hand and works great, it is super responsive and responds without any lag. The board is a little heavy, but the handle makes it easy to carry.
I've recommended Ownboard to a friend, so he bought one from Ownboard. Now we ride together daily.
You definitely need these cables if you want to do deck swipe with out destroying the original board.
