I was impressed with the quality and design of these bands. They come with two handles, which attach to the bands with carabiners. I especially like the design of the door attachment. Unlike the other band and attachment I have, this one just slips through the crack and is held in place by a clump of metal that's sewn into the nylon strap. When the door is open, you can poke the clump through the gap on the hinge side. When the door is closed, it's way too big to get pulled back through. I also like how you can hook two or more bands to the handles to create more resistance as you get stronger.
