Seems well made, but I haven't figured out why it gives off this repulsive odor -- like, if the material is made of this stinky stuff, or it's coated in something, and can eventually be cleaned off. I've been working at it, but it still stinks. Working out, and having this thing close to my face while I'm breathing heavy feels pretty unhealthy, actually.Otherwise, it's well made and does what you expect a dumb bell to do.
