What Fenlander said is accurate.
I tested one back in about 2007. Seemed to be of reasonable quality for occasional recreational use, but a world of difference is build quality between it and the mainline South African manfacturers such as Gemini, Caesar and Aquarius. The extra cost of those brands will more than pay for itself in the longevity of the product.
I believe the same products have also been marketed under the brand name of xtreme inflatables.
