Purchased in JAN2020 and went through the learning curve of how to set it and to manually run it. Your best option in JAN2022 is now the LCD version, which is more intuitive with blinking icons, rather than a single blinking light.Aside from that, the pump lasted nearly 2 years, while running every two hours.I have pumps on cat Drink Well Water Fountains that have never died, but their pumping mechanism is quite different, so I think 2 years for this pump is good.The screen and everything works; just the actual pumping mechanism has failed.My only clue was my dry, dying plants after I was away for two weeks.Nothing ever fails until you're not there too watch it. LOLI think Splant has provided a great product AND it's obvious that they paid attention to customer reviews because they now produce an LCD version.In electronics terms, an LCD is more complex and thus risks more possible points of failures because of the additional screen indicators versus the simple, single LED light as an indicator.However I think it offers more reassurance to plant owners right out of the box because you should see things like days, hours, minutes and seconds indicated on the screen so that there is no doubt that you nailed the settings and won't kill your plants.On this version, to MANUALLY START THE PUMP, after you've set the timers, simply push the center button again, while the screens/timers are still lit.In other words, one push to Power On and a second push to MANUALLY START THE PUMP.We'll see if the LCD version is similar or if they have a more intuitive manual start method.
