I used them for my front patio and planing to use them for the back patio as well. They are heavy so it is a one by one movement. Do not try more than that or you will have a few cracked ones. I certainly love the look and so the neighbors.
Pavers were a cost competitive option for my 12x12 paver patio that's easy on your wallet. My only complaint is that out of 96 pieces I purchased, I had 6-8 crack and once installed I have noticed some crack lines on a few. Hopefully those will not develop into a full crack and need replacing.
I did properly prepare the area with crushed gravel and sand and packed with a compactor so it is critical and hopefully will keep everything in tact.
