As you read through the reviews of this product, a number of criticisms are levelled at it. All these criticisms seem valid. The case is large: much too large to fit in your pocket. If the glove compartment in your car is large enough (and tidy enough!) you may find that it will fit in there. This is not just a case which you can slip your GPS unit into, and then slip into your jacket pocket.
The case has a number of internal mesh dividers. Two of them are zipped and one has velcro to close it. These smaller pockets can usefully accommodate spare memory cards or a camera battery (for example). The larger pockets can be used for cables, GPS units, mobile phones, chargers (provided the plug isn't too bulky) and so on. With the larger pocket, there is nothing to constrain the various items it may contain from moving around and hitting each other. Anything particularly delicate might benefit from a bit of padding around it.
As others have pointed out, there is no substantial internal padding. And, because the case is quite large (and not especially rigid), there is a certain amount of flexion in it. This does raise a bit of a question mark over how much protection it will offer.
When the case arrived I must admit to a certain amount of disappointment with it. However, it was packed with various bits of electronic gadgetry, thrown into a holdall, and survived a trip to Greece. In fact, I was grateful for any level of protection it offered to its contents as the holdall had clearly been handled quite roughly in transit.
If you are considering this product, keep in mind the criticisms which are mentioned. In particular, get a feel for its dimensions because you may otherwise be surprised by its size.
