I have a small patio, just 7x8", and the concrete is old and nasty looking.  About 5 years ago I purchased WOOD patio tiles from Wayfair.  They looked great the first year, ok the 2nd year and by year 5 they were completely rotted and disgusting.  I tried to cover as much as I could with an outdoor rug.  I'm hoping this composite tile will be much more durable.  I don't LOVE the color (Wayfair was out of the gray) but now the patio looks nice and clean and new.  They feel a bit plastic-y when I walk on them, but overall, very nice.  The neighbors like them a lot (I live in a condo community).  Also, they were very easy to put down and interlock.
