Wine Aerator from Williams Sonoma

This Twister aerator with decanter and stand from Williams Sonoma for $79.95 looks pretty cool for the wine lover - and from Williams Sonoma I imagine it's quality. I am just cutting and pasting what they say on their website, because it's complicated -- but I'm sure those in the know know what this is all about:

To reveal the full flowering of any red wine instantly, introduce maximum oxygen by decanting it through this easy-to-use spiral aerator into the matching glass decanter. The resulting difference in aroma and flavor is impressive.

• Patented mouthblown, double-walled, 3-phase glass aerator instantly multiplies oxygenation.
• Phase 1 catches any sediment while introducing oxygen as the wine flows by; phase 2 allows additional exposure to oxygen; phase 3 directs the wine through the spiral, dispersing it into the decanter. 
• Mouthblown glass decanter is specially designed to hold the aerator.
• Aerator has an integral stainless-steel sediment filter.
• Includes a stainless-steel stand for holding and storing glass aerator.
