Rated 1.0 out of 5.0 by Don't buy it will fail I bought this about 4 months ago and it worked fine. A couple weeks ago I noticed that the ground around the plants for this timer was saturated. The timer had failed with the valve stuck OPEN. I got my water bill last week and it went from around $120 to $175. I'll never buy another Vigoro product. The only reason I gave this one star is because I have to put in something. See attached pics. One shows the timer "off" the other shows the sprinkler watering. July 25, 2011
Rated 1.0 out of 5.0 by Waste of money My wife and I bought two of these last year (2010). The units worked very well....for one year. This year, I installed new batteries and tested the units - neither worked. On one of the units, one of the valves is stuck open. I hear the motor running to close the valve, but nothing happens other than a periodic click. Either the valve is stuck open, or the "brains" in the thing is confused and is trying to open the valve rather than close it. After a few seconds, the motor stops and the low battery light flashes. The batteries are good (I even tried another set of new ones), I think the flashing indicates an error. On the other unit, neither valve is open, but both motors run. Again I hear the periodic clicking, but nothing happens. After a few seconds, the motors stop and the low battery light flashes (error). For $40 ($80 total), I expected something that was going to last more than one summer. I even covered the units last summer to protect them from the elements because I wanted them to last - obviously a waste of time. Additionally, the units are sealed, so you can't get into them to clean them without destroying them. March 24, 2011
Rated 1.0 out of 5.0 Needs a clock I bought this two-zone timer so that I could water my garden and my lawn different amounts on different days. The lack of a clock - allowing you to set it to water at a specific time of day - is a major flaw in the design. If you want to water in the early predawn hours, which is when one should water in hot dry Denver, you need to be up at that hour to set it. That was annoying enough, but then, after a very early morning spent setting it, the unit short circuited after our first rain (my spigot is up against the house but not fully sheltered). You will be much better off buying two $20 single-zone programmable timers with clocks than wasting $40 on this disappointing and inferior product. July 1, 2010
Rated 1.0 out of 5.0 by What an utter piece of junk Took brand new unit out of the box and installed fresh batteries. Attached to faucet, set zone 1 to "on" and left zone 2 at "off". Zone 1 water came on as expected. About 5 minutes later zone 2 unexpectedly came on, and low battery light began flashing. I dismounted unit and opened battery compartment, to find it was completely flooded. True, the batteries are probably low now, after being shorted for 5 minutes. The valves appear to leak water directly into the battery compartment and electronics. If I put more batteries in, the value motors now just run continuously, opening and closing every few seconds. This was a brand new unit. What a piece of junk. June 18, 2015
Rated 1.0 out of 5.0 by Only worked one season Purchased summer 2010 and not working as of spring 2011. The low battery light blinking even when install fresh batteries. Tried different fresh store-bought batteries and still the battery light blinks. Valve froze in the open position. Else, very intuitive all-in-one design. Why can't products just work? Very frustrating. July 28, 2011
Rated 1.0 out of 5.0 by Very poor quality product Failed right out of the box. Valves cycled constantly and Low Battery light flashed with brand new batteries. Taking it back. June 7, 2011
Rated 5.0 out of 5.0 by Love it! This is the fourth one I have purchased over the past years. It is the only one I have found that can program two different lines. Not having an exact time to program has not been a big problem, I just go out about the time of day I want one to run and set the timer, then go back at the time I want the other to run and it's done! I have learned, the hard way to not leave them out over winter, as the battery compartment will get wet and die. Granted, mine are placed horizontally in the garden, not vertically as it would probably prevent this. The line was already in place, and I have not dug it up to change the configuration.

Rated 1.0 out of 5.0 by Not Happy This is the second Vigoro two zone timer that I have bought within a year and they both have done the same thing. They start leaking from the valves. It seems that after a very short period of time the valves do not shut down completely. Needless to say this will be the last Vigoro product that I buy. August 29, 2010
