While it's true that some may neglect or have trouble reaching their feet in the shower, there are a few alarming features of this product. First of all, those who may be unsteady on their feet must beware. Standing on one foot in a slippery shower is not a good idea, especially when you're about to make your foot even more slick with soapy water.
Is it good for diabetics? Many diabetics have peripheral neuropathy that causes their feet to be numb and they won't be able to feel if they're scrubbing too hard. This can lead to injury to their foot can even lead to infection. A better solution would be to use a brush while sitting to wash the feet. You'll know how much pressure you're using and will be able to better see what you're doing.
You also need to be concerned about buildup of fungus and bacteria on this device. It will stay damp, if not dried properly, and you can be infecting your feet and reinfecting them, causing athlete's foot and toenail fungus.
A search of Easy Feet also shows much consumer dissatisfaction with respect to the business practices of the company. Sending wrong orders, overcharging, selling email addresses, and not being reachable by telephone are some of the many complaints. This is another good reason to not purchase this product through the phone or internet.
