I purchased the 3by3 decking with pergola, the delivery was fine . But anything else was of a less quality. 1st I intended to install it myself but the instructions were not tailored to the product (decking instructions separate from pergola one) which defeat the whole objective of the unit. Unclear and useless. I contacted them several times to get clarification but they kept referring me to the instruction on the website. I had to pay a professional to build it. Then we found that the quality of the materials very poor : the screws get damaged quickly, so you can't un-screw anything. The brackets did not fit the wood so I disregard them altogether. The list is long but I am sure once you read other people reviews to get the message. Needless to say that I will not recommend them to anyone, Have fun trying to get answers for them Ben
