Have the Scholl Velvet Smooth Express Pedi for several months now with us in the house and use it regularly. As we have always used the last time over the rollers with the words "strong" and after some browsing on Amazon hear about this product "Extra Strength", we do not have long thought and ordered it. The shipping and the quality is without further ado as expected good, but my expectations were not really met by these roles.
If I roll order me "Extra Strength with diamond particles," I expect a difference as opposed to weaker levels of hardness - but I could neither a longer life, yet find a better or faster results - so I'm going to cheaper again in the future, but according to grab inscription not as heavily advertised products.
