Review (2/5): pretty cheap, but if you want the bare minimum, this should do the trick
This is pretty cheaply made. After a while, the metal begins to smell a bit rusty, and if you apply too much pressure, it completely stops rolling. It also is very creaky, which could be just a minor flaw to some people. I ended up replacing this with a much better. I would also pass if you're expecting this to be true jade. You're not getting a real, 100% jade stone for $10. (Article from fabfitfun: "Jade rollers priced under $9 are typically made of glass or plastic and don’t deliver the results that a real jade roller does.") You'll instead be getting stained glass, which is totally fine, but just don't get your expectations up. I'm sure the company will dispute this, but you can't convince me otherwise.
Pros: rolls, doesn't fall apart
Cons: creaks, stops rolling under certain pressure, metal rusts, not 100% jade
In sum, it's just a cheap jade roller, nothing more, perhaps a little less, but it gets the job done.
