We live in Texas and get a lot of wind. I had built my own lid which was heavy but didn't blow off. So, the tie downs are an excellent addition that should work great. My only thought for improvement would be to cover it with a heavy duty silver vinyl rather than heavy black vinyl. We get a lot of sun and heat. A light reflective color would be more effective at helping it stay cool and might not get eaten up by the sun as quickly as I suspect the black vinyl will. It is a great product!
