I used the products, I liked them but I had a really bad experience with the company - I needed a cover pink, they took my money, item was then out of stock, took 4 months of lots of phone calls etc, eventually my cover pink was delivered but by then I had changed back to NSI. Harmony are the only supplier in the country so I could not get my acrylic powder anywhere else. Due to the customer service being so poor I refuse to use their products as wouldn't be abs to trust I could get my order on time.
