Mothers Powerball Polishing Kit on Amazon - Good Deal?

I have never used these products but have seen them in Wal Mart & read here.
My Snowmobile club is going to have a pre-season get together to clean stuff up and was thinking of buying the kit to bring besides the chili

It is $76 bucks on Amazon & since I have Amazon Prime its free 2 day ship & no tax. So question is
Is it a good deal & do the products work?
You get everything in the picture.
Advertisement says you save over $70?

 

I have always distrusted these type products.
A bit of grit getting lodged in a spinning sponge ball just dosen't seem good.

 

I know it's a little late, but I've tried the power ball products on several different types of rims and didn't care for it. I got better results with a micro-fiber rag.

 

I use one on my 20in chrome wheels and also used it on my Harley. But used Turtle wax. All I have is the big red ball

 

Separately, each of the "Powerball" items sells for about $25 in my area, so if you do the math, the combo price seems like a good deal.

How well the products work is another discussion......

I have the original Powerball and have used it with my battery drill on a multitude of surfaces (wheels and paint) with various products with success.
