I was hoping for and expecting it to quiet things down at 55 mph and above, based on comments on this forum. I am amazed by the difference it makes, worth every cent. Worst top noise now is a little wind noise coming from around the driver's door. That would be there with a hard top.
I no longer have to have the fan on to keep the top inflated to cut down on buffeting on the highway. A night and day improvement. And there is a $50 off rebate in place to October 31.
Thanks for the sound advice!
