This 10x13 pergola is honestly a beauty to look at but a beast to set up by yourself! I'm okay when it comes to assembling things but in this case it is highly recommended to have 2 competent folks at minimum. It took nearly 10 hours to complete construction mostly by myself. The paper and online video instructions are VERY important and both should be reviewed together. Even with the information, some steps are a leap of faith and could include more details. I've seen another pergola's assembly instruction and that one uses lots and lots of screws. Not this one however as it emphasizes "use a lot of force" for some steps. A rubber mallet is recommended. Fortunately, the aluminum parts are very durable and withstand lots of punishment. I am confident about the construction of this masterpiece. The hand crank is satisfying to use and the LED lighting is bright enough at night. I took a chance with this Causeway Bay brand and it delivered! I still need to attach the optional 4x blinds and there doesn't seem to be mounting holes on the pergola. It would be a shame to drill holes into it but I will update the relevant blinds page whenever that time comes.
