I'm aware that Victa, in particular, used to sell mowers under various store names, but that wasn't likely to fool anyone I think. The companies like GMC, Pope, Sanli etc seem to have a business that consists of finding a Chinese product that might sell here, getting the manufacturer to put the importer's brand sticker on it, bringing in a sample, and peddling it around the retailers and chains. The only value the importer is adding by putting his brand on it, is creating the appearance that it is a branded product, not an unsupported Chinese no-name product. Whether the warranty on those brands is actually valid is something that can only emerge with time. However most of them seem to have frequent changes in models and products, so that a few months after buying it, the owner may find that it is no longer listed on the brand's website, spare parts are no longer available if they ever were in the first place, and the service department thinks he should chuck it and buy their replacement product.
