I bought this with the Premium Work Mat (they're available as a bundle, or separately), and they turned out to be really worth it. I had been changing strings by propping my guitar neck up on whatever was handy, while the body kept sliding around on the table. It was maddening and also was just inviting a serious accident. The cradle and mat keep everything in place. And as someone else pointed out, they do not stink! Many such products are made of materials that smell awful, but not these. Highly recommended.
