Variable ND Filter

Has anybody used a Variable Circular Neutral Density Filter on the D3100 and found they are successful?

I have used one. It is useful when you need to take pictures with flash during bright sun days as the D3100 has no AutoFP function. I have used a cheap filter only if you don't have a better one. Try to avoid direct sunlight in the background due to reflexes.
