Review (5/5): Strong, powerful, effective, yet gentle.
Arrived on time and as describes by seller. Works very well I bought this for my gypsy grandma who has callused feet. The best way to use it effectively is charge it for 10 hours when you first get it. You can do that by plugging the usb into the wall or a computer. Soak the feet in warm water (for best results add salt to water). Leave feet soaked for about 20 minutes then towel dry them very well. Unplug the thing and start using on heels, or any area with extensive calluses. Make sure you move it back and forth don't just hold it on one spot otherwise you will hurt the skin and damage it. You'll see little fine dead skin falling off. It's a gentle yet very effective method. Be patient and treat the feet well. Very useful in people with diabetes and high risk for ulcers. Don't use if an ulcer is present, a podiatrist is better suited to deal with those. Don't use on open skin at all. Highly recommend this powerful item. Charge frequently so it's always ready.
