Checking on an economical plant watering system for a neighbor

Checked on a neighbor’s plant watering system. I set it up for them in December, and it’s been working perfectly for six weeks. The controller (with a built-in pump), tubing, and drippers cost around $35. The only drawback is the controller’s battery, which needs recharging about once a month. An $8 smart plug allows them to remotely initiate charging from Arizona.
