No offense taken Momoney. I should have been clearer in my posting. I know what they are supposed to do. I was just wondering if they actually worked like they are supposed to in real live trading. Thanks for your input by the way.
I'm not as sophisticated (yet) as Riskarb, Maverick or Mo, but will try to answer your question with an example.

"My VIX options aren't working!!

Over the past week, I have probably answered about 100 calls and emails about why long VIX call options haven't gone up as much as people had hoped with the VIX index itself rising so high. And why do they seem to be trading below parity? Are they just giving away money in that product?
A case in point are the June 15 calls, 1.90 - 2.10 with the VIX cash at 18.25. They're 1.25 under parity, looking at the cash. But the June VIX futures are trading at 15.70.
The Aug 15 calls are 1.95 - 2.00. The Aug futures are 14.80.
The Nov 15 calls are 2.15 - 2.20. The Nov futures are 15.50.
Each one is under parity if you compare it to the cash VIX. But what's happening is that the market makers are pricing the VIX options off of the futures. And if you look at the futures, they're telling you that they think that the VIX will be lower in the future than it is now. If you're a VIX market maker, you're hedging your delta risk with VIX futures. So, you're watching the VIX futures move up and down and pricing the VIX options accordingly. It's the same as the OEX and XEO market makers pricing those options off of the S&P 500 futures. Also like the OEX/XEO, you use the future as a hedge because the actual underlying index (a basket of 100 stocks for the OEX, a variance swap for the VIX) is very hard to execute quickly.
That's something that you have to understand if you're trying to bet on the direction of the VIX or using as a hedge (however imperfect) against your long portfolio deltas. Even though the VIX index is moving up or down, the VIX futures may be doing something else. You can see delayed VIX futures quotes at this link. Try to get an idea of where the VIX futures are before you trade the VIX options. "
This gives an idea of what to expect. So even if VIX cash goes up, VIX futures might not. Hope this helps.
