My girlfriend bought this set for me and I fell in love with it. These colors made the set I was using before seem like Crayola watercolors. The vibrant colors that are left when your work drys is beautiful. The trays that are built in aren't too bad, though I tend to use my own watercolor trays. The brush that comes with it is a really good reasonably priced series. So if you like it, it won't cost you much to add more to your collection, I own from sizes 0 - 8 in the round tip model and the designers tip model and spent a little over $100 for them. Then you have the replaceable pans which makes it so much easier and cheaper to replace colors that you love and use more than others. There is also room to add 8 additional colors of your choice to this tray. There are many colors in this series for you to customize your tray with, leaving you with your perfect color palette. Additional pans run about $10 each which is another great thing considering how long a single half pan last. This is an all around excellent product that I highly recommend.
