There, you say, "ah, anyway, ten euros for so little, shall I let it roll spot me?".
Actually no, this roller can be worth it, provided you do not dwell not on the price per liter (which in any case has no real meaning).
When dawn feels a headache, heaviness in the neck, or even a shot of stress, just shake the bottle, remove the plug and move the ball on his forehead (at hairline) on neck (ditto), and / or behind the ears.
The smell is pleasant (unlike Puressentiel - Roller Stress 12 essential oils - 5 ml whipping a little, it must be said), and the effect freshness, due to the essential oil of mint, do not wait .
As regards efficiency, it is enough relative. Sometimes it relieves a little, sometimes not at all. Do not expect a miracle against headaches but see it rather as a comfort.
In reality, it is the practical design of skating that is interesting. This is a portable solution that can be daily self. Worth a try if you really feel the need, at worst it can not hurt.
Thank you for having me read.
