Product arrived quick. After using a half moon spade to start the outline for the edging outline, I found it somewhat difficult to install without damaging the first panel somewhat. I decided to soak the area with water and waited until the next day to continue installing these edging panels. I found using my pressure washer with the sharp stream tip on it made it way too easy for installation with minimal hammering in force required. Trust me, the pressure washing sharp stream Tun to cut out the groove where the panel will be installed will save you so much time and aggravation. My yard is heavy clay. Pressure washer made quick work of it.
