We had trouble finding water timers here locally because of the dry weather. We bought two of these and they work well. However, setting them up requires that you start watering at exactly the time you want to water every day. That's great, but if you want your daily (the only watering interval this unit will do) watering to happen at 4 am, you'll have to get up at least once to set it at that time. Then when you replace the battery, you'll have to get up again at 4 am. All in all they've been dependable. Just understand the limitations of the product.
