I read the reviews on this and decided to give it a go. A lot of reviewers said the product was empty when they received it - I thought mine was because nothing seemed to come onto the brush. The liquid is clear and minimal comes out each twist but it works! Just dip in water and it froths as you clean. I was so amazed I cleaned everything that should sparkle - diamonds, gem stones and zirconias. Brilliant! Will order again.
