Had a couple of issues after install & customer service was professional, empathic & friendly. She took care of the situation to our satisfaction efficiently & without any additional pain. 
The product looks overwhelming at first but went smoothly once you caught on to the instructions it was a breeze. Definitely need at least 2-3 people but 4 would be ideal. Very heavy so not really worried about 20 MPH winds. Highly recommend this pergola without hesitation.
