How does this stuff stack up for home studio applications?

C'mon, I'm serious. This product was on the telly last Wednesday (the 1st link goes to a vid of the demonstration on an Inventors program). It looks too good to be true but is it.
The claim is that it's rated as better than Rw + Ctr = 50 dB or AAAC6 or something.
The wall only has a 15cm profile of plasterboard, membrane, plasterboard, staggered studs, plasterboard, membrane and finally plasterboard.
I'm quoting from their website with:
It is a high performance drywall noise barrier that delivers exceptional performance due to it’s patented constrained layer membrane.
* Exceeds BCA minimum requirements for airborne sound insulation for a wall between attached dwellings
* Meets the highest possible AAAC acoustic rating of 6 stars
* Rw62 and Rw + Ctr = 55 dB
* With the thinnest possible wall section of 148 mm
* Most economic 6 star rating wall system available
The flexible visco-elastic membrane consists of a patented constrained layer membrane, combined with vibration damping material ‘floating’ elements. At just 1.2 mm thick it is easily handled and can be installed by just one person.
The visco-elastic membrane can be penetrated without any degradation in performance. The finished wall system has a solid feel and when impacted upon, sound resonates similar to a masonary wall.
It also controls the large coincidence dip in the upper-mid frequency region of 2500 - 4000 Hz, which typically occurs in plasterboard walls.
It looks good as well as being reasonably cheap. Any comments.
