The price is great, at least at first glance. It gives you 200ml compared to other more expensive products that give you 100ml. It seems four times cheaper. As I said, it seems, because in the end it's not!
The Arnica oil inside is only 25% in the jar. The rest is sunflower oil. That's why it's very runny (so it doesn't stay well in the area you want and it stains - it flows more intensely and drips instead of staying in place). It has nothing to do with a similar product that costs four times more, which turned out to be worth the difference. You get what you pay for. Because I don't like the oil base. What's wrong with it being 100% Arnica oil instead of just 1/4 Arnica? If I knew this detail from the beginning, I wouldn't have bought it. However, I haven't looked to see if more expensive products are 100%.

Edit: A month later, when I had a sprain, I used it intensively in several massages, in a large quantity (with a handful). It probably helped me a lot. I had a strong and fast recovery. I will remove the part where I said I wouldn't buy it again. It does a great job. You can apply it generously without hesitation. However, it flows more intensely and stains twice as much. If I find something with a higher Arnica content and not something else, I won't mind spending a few extra euros, proportionally.
