Query: Save your money. It doesn't work.

I have very thick toenails so this product looked to be a godsend. I followed the directions exactly. Final analysis? Doesn't work. Save yourself some money and do this instead: fill a large bowl or bucket with very warm water and either bath oil or olive oil. Make sure you have a towel for your feet, and a good book or magazine to read. Soak your feet for at least 30 minutes - 45 is even better. Take one foot out of the water, pat dry and cut the nails Immediately before they start to dry and harden. Keep the other foot in the foot-soak while cutting the first foot's nails. Then repeat with the other foot. If your nails are still hard to cut, soak for longer. This of course works really great when someone else is doing the cutting and all you're doing is soaking and reading :-)
