This arrived on my doorstep and I could hardly wait to get it out of the packaging thinking about what an easy way to care for feet! how right I was, after the first use my feet were already feeling softer! So very easy to use, just smooth over areas of hard skin and the Scholl Express Pedi does all the work! After buzzing around my heels and big toe where the skin is hardest, all I did was apply some Scholl Velvet Smooth Intense serum and my feet felt like they had been treated to an expensive pedicure. This brilliant gadget is operated by batteries (supplied) I was very lucky to get mine for free on BzzAgent, I see they cost around £30 in Boots. I would say that is money worth spending to be honest. So much easier than struggling with a pumice stone, so much nicer to feel and look at nicely looked after feet. Scholl Express Pedi. Specially made for summer feet.
