So the advertised as waterproof shell plastic case is absolutely cheap material. Feels so on, and is in fact so fragile that I got a broken shell. So good only as packaging. In this respect, I also did not need a spare because eh flies in the garbage. The large carabiner is great, closure is fixed and is still comfortable on. Is greater than expected, the material is very stable. The small carabiner is mediocre because of the closure makes a wobbly impression. Let's see how long the holding.
