Instructions were easy to follow once we got all pieces sorted out and separated. It took a total of 12 hours to complete. I did most of the work with my wife and daughter helping out when I needed an extra hand or two. Its been a little over a year now and the gazebo is still solid and looks great. I would recommend using an 8 to 10 foot ladder to attach roof and panels. I only had a 6 foot and found it very challenging to reach top to secure screws. We installed a shade curtain, a small ceiling fan and misters and boy they help on a hot day! I would totally recommend this product. I went through 3 cheaply made canvas top gazebos in 10 years. I feel this will last 20 years or longer. Well worth the extra money!
