It's not as time consuming as walking the property without a remote. One time investment and from then on you are benefiting from it. After a few installs you pick up some speed. I used a dewalt power screwdriver and set it at 7. Some controllers go really fast. Others are a total pia especially if they use speaker wire style connectors. RB ESPM is by far my favorite for pigtails. WM SL is my least favorite. Lawn genies are a piece of cake. As long as it has screw terminals. A few of the older toros that require an eyeglasses screwdriver are a pain. The original ESPs with the terminal going up and down in the back of the cabinet are a total pain. The RB mechanical RC is a pain especially if it has a master valve because of its design to allow it to be put in a series as slaves. Still it was worth the trouble on every one especially if I knew I was going to be back.
