## Questions & Answers

**Q: how many dose it come with/ is it a rip off?**
A: ONE, (1) ball!! YES IT IS A RIP OFF!!!!

**Q: Is it just one ball?**
A: YES, YES IT IS JUST ONE, (1) BALL!!  I was so Damn Flabbergasted, not to mention the stupid I was feeling for getting outright Bamboozled that I didn't do anything about it!! It is stuck in the wall right next to my computer with a sizable Bowie Knife, in it's original zip lock bag stapled to the invoice just as it came in the envelope. I'm looking at it now and see it continuously, constant reminder of the Integrity Challenged Sub-Human's that walk this planet and should not!!!!   As my Grandmother once said to me,  "Kev, Sometimes that Stupid Gene just jumps up and kicks ya right in the A**, doesn't it?"  Yes, Gram, it does!

**Q: What does the ceramic ball grade 10 do**
A: Well, Mine is in the original small zip lock bag which is still stapled to the invoice it came with and is stuck on the wall in front of me with a Bowie knife. There as a constant reminder that there are a lot of less than reputable companies doing business and should not be!!! That is what my 6mm, Grade 10 ceramic ball does.
