Edit: is it just that they are a German company?

Yes, they are.

It’s really strong pepper spray, you spray it between you and the bear, towards the ground approx 10m from you I think. They do come with instructions though, please read them before use.

What’s the difference between black and brown bear poop?

Edit: it makes sense to make oneself heard, the worst thing that can happen is quietly walking around a corner and there’s a bear with two cubs close by.

Bear bells are a bit annoying and clapping or just talking to each other also works. Humans are not considered bait for bears and they will usually try to avoid you.

There are good books about avoiding bear attacks when in the backcountry.
