This machine was AMAZING! I cleaned my fiance's necklace that was extremely dirty, the machine pretty much cleaned off everything on the first go but i did another one for good measure. I washed a lot of other jewellery and it worked just as well on every last item. I have to admit i was entirely impressed. It was slightly more noisy then i thought it would be but overall i give it a 5! I would definitely recommend this to anyone!
