I have 8 valve total and will buy more in the future. They are great, no wires , so you can add a new zone at anytime without worry of running wire and timer. I change batteies about once a year. Very simlpy to program and maintain. Great item. Joe

Great water flow and simple operation. If you do not need a back flow device, this valve is perfect. Much greater water flow with this one over the model with a back flow. I now have 7 of them working fine for over two years without failure. Just replace the 9V battery about every 6-8 months with it operating daily. Excellent valve.

I have had this product for six weeks. The timing and durations mechanisms on the product work really well. I have two sprinklers running off this timer and there is enough water flow to power both sprinklers. In week 6 of use, the product developed what appeared to be a leak within the mechanism. I called DIG technical support best to call first this in the morning, 8:00 am Pacific Time. The technical support rep asked me to first try applying a small amount of silicone grease on the internal O ring. He talked me through how to open the mechanism pretty simply and where to apply the silicone grease. Now the product works fine. No leaks. The tech rep indicated however, that if this fix did not work, he would authorize a return of the product either for repair or replacement. Counting the time it took to purchase the silicone grease, the do-it-yourself repair took all of 30 minutes.
