We did a carve stone patio extension with them at our last home. We were happy with it overall. Positives - looked nice, cool to walk around on barefoot even in the summer, less expensive than actual flagstone. Negatives - more expensive than stamped concrete, the texture traps dirt and required pressure washing more frequently than I would like, it will need to have the color application redone every 4-5 years or so, and I could notice hairline cracks in the surface starting about 3 years in and while they weren't really noticeable, it did bother me. Overall, if you like the product, I would recommend them.
