Very stable and highly recommended ...

I own a Lenovo Thinkpad Edge 11 (11.6 "with battery back on standing). The protruding battery my laptop fit not in the standard case. The case is a little too large (on one side and above about 4 cm square), but fits as well as the charger with pure (see picture). So far, I always had to take the charger separately, find it really handy now everything in an envelope to have! In the notebook compartments of bags or trolleys that cover fits more purely.
This hardcover is definitely more stable than this neoprene case. It is fed from the inside and has a soft surface. The zipper is sewn clean, has large (but not too much) Zipper and runs very easily.
The only (tiny) downside: the inside straps are sewn (see picture) that hold the cover at about 45 °. Unfortunately, this can not be solved, but in my opinion does not necessarily lead to a devaluation.

-> I am very satisfied and no longer give it ago!
