I bought this a few weeks ago. I bought 7 colors in total. I was surprised by how powerful the colors were and how easy the product was to use. For me, adding the product to hot water seemed to be the easiest way to get it dissolved quickly. All of the colors seemed to adhere to the wood very well, except for the golden yellow color. That one never seemed to be bright enough for me. I will try a different yellow next time. All in all I am very happy with the product and will continue to use it a lot in the future!!! I just hope their color selection keeps growing!!!
