We purchased two of these for our conference room where we do a lot of interactive work with clients. They get a lot of use and everyone - including the clients - loves them. We found it easier to spin the boards around, rather than flip them over in the frame, to use the other side. (There is whiteboard material on both sides.) There is a nice tray under the board for markers and erasers and the casters roll smoothly on our office carpet. The wheel locks do seem a bit fragile so we don't allow people to use their feet to lock them or unlock them (fingers only).
