Does anyone have one of those sails for the garden?

Looking to make my garden a little more habitable during the winter and I've seen sails that you attach at three points. I live close to a main road and and slightly concerned that a gust of wind could blow it away?! Does anyone have one? Are they good?

Yes, we got one. It's really good. I haven't worried about it blowing away as it's quite sturdy and it's also pretty easy to angle it so that it doesn't catch the wind (ie., fairly flat).

they are good - have had several - but... you need to make sure they are incredibly taut and at the right angle - otherwise, water will pool on them and they sag... wind - not an issue as long as they are attached to substantial structures (we had them on a building at one side (wooden shed) and fence posts the other and that was fine...

They will be no good in the winter.
We have one to shade the decking in summer, we made the mistake of leaving it up one night and we had heavy rain, despite it being taut and angled, the water pooled and it was almost touching the deck so it’s now saggy down the middle seam.
It wasn’t a cheap one either.
A weather proof gazebo would be better or even a plastic tarpaulin that has attachment points, like the ones on market stalls.

mine stayed up all year - as long as they were taut and at sufficient angle (they specify what it should be) then no pooling of water - snow - it would hold a day's worth, so had to go out and push that off every day...
