I was planing to buy 2 of those kits. For those of you who have done port polish work, think this kit is any good?

If you buy 2 and they are no good you are out of pocket $20.00 plus postage.

If they are fine you got a bargain.

What can you get for $20.00 nowadays that will keep you amused for hours?
