Used plenty of them in the past. This one was easy to hook up, both electrical and plumbing. Wired it in to a switch on my tractor to select the boom, and a second switch for the pump. NBD!

Quality built, affordably priced, flawless performance. Added it to my tow behind spray rig, it replaced a manual ball valve."This was fine for long continuous treatment of fence line or roadside ditch, but led to a lot of waste when the tow cart needed to be stopped, and I had to run back to turn the valve. A simple sealed 12v motorcycle battery, a few terminals clips, a toggle switch and I'm in business!
