Query: Low cost but also low quality

I've bought a number of these covers, mainly because of their low cost, but now I'm thinking of trying another product. These covers don't necessarily fit all saddles well, often being too short one direction or the other. They also tear very easily in the area where there is an opening for the stirrups and this has happened to every one I have owned. A plastic garbage bag cut down the middle and laid over the saddle would probably work as well.
