Has anyone tried the PlaneTalk system?

I ran across the PlaneTalk site and it's certainly got my attention but don't want to spend $80 with shipping if it's not worth it.
The reviews are all very positive but you never really know if it's the company writing them.
Anyone try PlaneTalk and if so would you recommend it?

Here's the site

Did you end up buying it? What do you reckon? Is it worth it?

I was wondering what level of player this would be aimed at. Would also like to hear more views on its effectiveness. Thanks for the posts.
