It the greatest product line EVER!!!!!! :-)
Loved the kit (got the basic) that came with steps 2, 3, and 4. However I would HIGHLY advise towards being super careful with the bottles. While the product inside of them is a high quality, the packaging needs some work. Step 2, being what helps the powder set, has the smell and consistency of crazy glue and needless to say that after a couple of uses the top of the polish bottle stuck to the bottom and even after submerging in acetone and water to try to remove the glue keeping the two together, the GLASS bottle shattered all over my hand and jeans when I twisted it the final time. Super upsetting as I now have everything from my kit except step 2!
