"Smart VOV": Variable Orifice Valve for ACs

[Christopher Gharibo]

Has anyone used this device in their AC and does it make sense that it'd
improve the performance as advertised below?

5° - 12°F colder air (at hot idle)
Reduced compressor load and extended compressor life
Improved performance when converting from R-12 to R-134a
Improved city fuel economy & emissions
Improved performance in factory R134a systems

Thanks,
Chris
