Yup, you're right. The Brand back then in the 90's was "Brake Guard" they ran into some trouble when the National Safety Institute BlahBlah in the US ran a study and found that the product does not work like ABS breaks.

The guy selling the device has replied to me that the item he sells is practically a clone of this Brake Guard Product.

Although Brake Guard got sued by a US govt agency and were prevented from calling their product an "aftermarket ABS" they are still available in the US Market, selling mostly to trailer trucks.
