I bought two of the Air Gizmo Gust Locks and have to say this is one product that didn't last very long. Their GPS docking products are great, but the strapping material used on the Gust Locks is of poor grade.
It is NOT sunfast or durable enough to withstand prolonged outside weather.
My pair faded in a week, and the strapping material has already dry-rotted and broken in only 2 1/2 months usage.
One would hope they switch to a better grade material soon and hopefully I can get them to replace the current "remove before flight" strapping material in the near future, otherwise I think I may resort to creating a set like Mel did and trashing the Gizmo Gust locks.
