Actually I was so far reasonably happy. It is reasonably stable - at least the Navi has taken no harm in time, although it really is always in my backpack. Just in case you might need it sometimes ...
At the corners of the zipper has ever want hooked a Bissel, but nothing wild. When I used the Navi again today after a long time, my tongue is broken off the same when you open the zipper. I use the Navi very rare, therefore is a material fatigue excluded because of frequent use.
But to get the slider without the strap around the corners is unfortunately almost impossible, which is why the case is now unusable.
From me therefore a very clear recommendation, prefer to invest the money in a clever alternative. This bag is in any case not worth it.
Addendum: I've now bought a bag of Hama ("Hama NaviBag Dots Blue") This part is also not processed insanely great but makes especially the zipper a much better impression than the Navigon part! The hardness of the material is the same in both bags in about. In addition, the Hama-bag has a chance to attach to a belt and a wrist strap.
