One of my posters was bent. You definitely need a power drill.  The fabric is a joke, will blow away with the lightest breeze and may cause damage in your yard because of the light weight poles.  The weights on the fabric doesn’t hold down at all.  My fabric straps ripped apart the same week of use.  I’m currently looking for a better solution for the cover/fabric which I’m seeing is between $100-250 for the cover/fabric.  Not worth the price and having to buy a more suitable cover almost immediately.
