We ordered one box as a sample.  The tiles seem to be of good quality, and easily assembled.  After purchasing the first box, we decided to go ahead to purchase 25 more boxes to finish our project.  We'll let you know what we think after we finish our deck.  Edit 7/6/2020:  We finished our deck in 2 hours.  The tiles were laid very easily and they look great.  I'm glad I made this purchase, as my deck looks 100% better.
