The product is excellent, even better than some of the other, similar items available on the market for the GoPro Hero5.
The FOAM is of excellent dual-layered quality, where the firmer side gives the whole structure rigidity and the softer part (the largest part of the foam structure), gives the product protection. The ZIPPER is of excellent quality, protected by an overlay on the outside that peotects the contents a bit from splash water. The case is of course not water proof but just spray water resistant (which is good enough, since the GoPro Hero5 is waterproof on its own. The LOOK & FEEL is premium.
