This cantilever parasol is substantial and reasonably well designed/constructed. However unless you have the base set into the patio with heavy bolts (or concrete), the angle and leverage pressures make it unstable. Even with a 70KG base to hold the unit down, anything more than a breeze (like a light gust of wind) will topple the unit crashing down onto your table. The base options need to be clearer and explain the potential danger of it toppling when the canopy is fully open. It has happened twice in 3 days and not particularly windy conditions.
