This sail is good quality. Speciality of note is the quality at the connection points. I have used Colourtree before and even under windy conditions, the corners held, even to the point of the connection coming loose. We chose to connect to the house with stainless steel pad eyes, plastic coated galvanized cable, and galvanized cable clamps. The connection must be very secure and sturdy as wind really puts a lot of load there. Use longer screws than those provided with the pad eyes to get as much strength as possible.
