I rely on safety chains to get to my home in the mountains in Montana during the winter. While you can get a bad item with any product, the negative reviews seem to focus on buying the wrong size or not being able to attach chains to the property. I can't talk about the latter here, but the video explains how to find the right size to order online. It is much safer to create your order based on the tire size rather than the make, model and year of your car as with used cars someone may have changed the tire size.
