Very good product, strong, waterproof, easy to use, nice design, I will just tone down the time it takes to synchronize the (average 2 minutes), sometimes it is immediate, sometimes it takes more than 10 ' and still nothing, probably from the novelty of the product. It does nevertheless a good investment, what pleasure during transfer photos to iPhoto to see the positioning especially when you travel outside France, is that you made a slideshow with the geotag.
