I have installed four of these valves + controllers on my property and I am planning to add another valve to one of them. They have been running flawlessly for a few months now. They solve a big problem as running wires to these location is far too difficult to be worth it. The only minor detail I would change is the flimsy design of the support bracket which puts it up on the top of the valve. These are well sealed and what I really like is the ability to take the controller unit out of the housing so it can be serviced and set. In sunny locations, I have added a wooden box over the valve unit (from IKEA) which is designed to allow me to turn the box over on top of the valve and pipes, and allow removal of the top of the box (which would normally be the bottom). This keeps the direct sun off the unit and the pipes which will otherwise degrade in the sunlight. In that case, I am not using the bracket but setting the controller housing further down in the wooden box.UPDATE -- after a year of using these, I have found that the sealed case will not successfully make it through a winter in the yard without cover from the elements, and the lower half of the box will fill with water, ruining the switches that turn on the valve. I will be pulling these out of their remote locations and putting them in a dry area during the winter months. The electronic switches in the base are what I tend to have trouble with.UPDATE -- One timer continues to go on over and over, have had to take it out of service. The valve is still fine, but the electronics only is what I need to replace now. The programming seems to have a bug!
