Def recommend, Ive had mine a year, I had really manky feet too, about an inch of hard horrible skin but I now soak my feet in a bowl of neat lemon juice for 20 minutes dry then use this and they are brilliantly soft. I find that if I dont soak in lemon, not much comes away but after soaking the hard skin is far easier and quicker to remove.
Ive not used any other s&g product other than this and their skin scrubs, which are also really good-if youve got those little bumps on your thighs or tops of arms, using those gets rid
