I'm very pleased with my purchase.  I read several reviews before I ordered and here's my follow up to the reviews I read.....1. the wholes do line up, but if you tighten the screws down then move to the next one on the piece you will cause the holes to go out of alignment.  It's better to tighten them just enough to hold it together and get your other screws in then tighten them all the way down.  2.  the instructions do not list tools I used a philips screwdriver both hand and power that had a fatter head.  the included alan wrench and a rubber mallet.  The mallet helped me with the installation of the roof panels I did not beat them just a little tap tap to get them into the right position.  3.  I secured this to my deck there were holes to secure it to the deck but not bolts.  I purchased 1/4" hex bolts to secure the feet to the deck then used the rest of the securement bolts included to secure to the house wall.
