I love that it's so simple to use! The program was very intuitive once I got used to it. It took me about 5 minutes to figure out how everything worked after using another program before. Also, there are tons of tutorials online if you get stuck at any time. There really isn't much else you can say about this product other than that its great! I am having difficulty with creating my own designs but other than that I have no complaints. This has been an awesome tool to help create custom pools in under 30 minutes!
