Work great, even with 25+ mph winds! The canopy started to twist a little, but the feet only move 2-3 inches. For the price I expected much less. If you can, use coiled stakes, but I was on concrete! The bags have heavy duty grommets for stakes. Also, use a course sand, as I used paver sand at first, but the powder in it would come through the nylon. Changed to play sand, and have had no problems since.
