Is a wind deflector worth it for the 02-05 Thunderbird?

I looked at them a bit a few months back, the cheaper ones and the rather expensive ones. I don't feel aggravated enough with air turbulence at speed with the top down to justify one of these devices....and they all look rather klunky and a pain to install/remove...
 
my Windblox takes 30 sec on/off and leave it on with soft top, up or down.
the Windblox is different because its solid and not just screen.
