im sure it works. its deff cheaper than a parts cleaner

the only problem i would thin you would run into is if the jewelry cleaner can handle the gunk off the chain...probably more of a problem than anything that comes off a watch

and you wouldnt really be able to just drop the chain in there and go about your business. dirty cassette+dirty sprokets+clean chain= everythings dirty. and the cassette looks too big to fit in there.

either way, 100 dollars aint bad to try it out
