Needs some refinement 4 I purchased this to use with my new Surface Pro 4. The interior was just a little too large, the device had too much movement . I personally did not like the color and feel of the materials used in it's construction. The design intent was good. The lack of a zipper was the main selling point. This sleeve actually was perfect for a Lenovo 11e I have. tommy Rutherford NJ 2015-11-18
