EcoFlo Black Widow Bucket System

Hello, wondering if anyone has used the EcoFlo Black Widow Bucket System?

http://modularhydro.com/ProductReviews/Black_Widow_Hydroponics_Bucket.html

Just researching single bucket DWC complete systems. Why the Black Widow bucket system seem interesting is that it doesn't use an air-stone but they're proprietary "Air injection technology (AIT) Spiders with air lines"

Anyone have experience with this system? Got different single bucket system you recommend?

Thanks

I wouldn't spend $50 on that, when you can build your own for less than $20.

You can buy better diffusers than that http://www.hydrogalaxy.com/hydroponics/air-stones-valves/double-micro-pore/?catargetid=120146710000012857&cadevice=c&gclid=CjgKEAjwwuqcBRCSuoivmIPnkwQSJACpqj3ksysrXrmbr8itF4S9MkOLvr_EXI9UkYKiOcwBvJDep_D_BwE

Yeah...that guy is trying to reinvent the wheel...conventional air stones are better and much cheaper.
