After a month    We put this into our deck boards AND an extra 2X4 underneath.    We continuously find screws that have come out.   On the third day, we had a thunderstorm and some wind the results being some bent supports and torn spots on the canopy.   Today we have 25 mph wind with some higher gusts, and our lovely deck gazebo is toast.  Broken supports, more bent supports, and additional tearing.  The directions were difficult to follow, and it took a long time, but it seemed great once put together!   We added some 2 x 4 blocks under our deck and screwed it into our decking and then the 2 x 4s.   Do not purchase this if your weather is not calm and nearly 
perfect.   Would love some compensation for a product that didn’t hold up.
