clearly, it is not a real foot massage, it is not capable of massaging between the toe;) having said that the product is still not bad indeed dailleurs first use you may make shavings, because it really makes a funny effect (between tickling and massage but you get used very quickly) so for addict relaxation by the feet, it's worth it. it is possible to adjust with or without heat, but personally I n uses no heat. it is possible to really choose the place where we want to be massaged by moving his foot on the object.
