The design "Black II" is thicker, but more stable. The Waking / sleeping Place also works. The lid is held closed by a rubber band like a Filofax. The Tab is inserted laterally and sitting in total firmer. The leatherette surface is softer. For placing the back is angled center and asked the longitudinal edge of the tabs into different grooves, which is essential stable and more flexible than in the colorful. In addition, in the folded state back mounted strap is safe totally practical and particularly when one-handed hold.
I have stuck in two Womo Kletts on the dashboard and the soft counterparts on the lid (black II). So in the erected state, it serves as a go Navi / Media Centre, which is securely attached and clearly visible.
I have both versions for Nexus 7/2013 and can recommend both depending on the use case. And for the price you can not go wrong.
