Easy to set and functions wellLo usé para una nevera grande y se dañó rápido, utilice otro en productos varios y funciona bn, no lo recomiendo para producto de mucho consumo, pero fuera de eso trabaja bn!.I use this brand timers to regulate pumps for three hydroponic Dutch bucket systems. They have been very reliable. One of them had problems after 3 years of continual use April-October each year. I bought these 2 to have a spare available.I use this as a timer for a mister for my chameleon's terrarium. I set it for 5 mins on, 15 mins off in a continuous cycle from 8 pm to 6 am. If this is what you're looking for, it absolutely does the job,and it works great. its not the easiest to set up, but the instructions are pretty clear.Works so well that I forget how to adjust itsuperI've only been using it for a week, or so. But it seems to do exactly what I hoped for. I'm using it as an On/Off timer for a hot water heater circulation unit we have. It seems a waste to have the circulator working 'round the clock every day, when we really only need it for peak hours (2 of us living here at my home). So it's great to set up the hours of peak usage for the water heater circ, and shutting down other hours. The way I set it up, saves me around 12 hours a day in electricity and potential gas-burning, to continue circulating hot water around my big house. The timer has a lot of options, but I really only need the On/Off at 2 different time cycles a day.I check on the timer every now and then, just to see that it is keeping time... and doing what I've asked it to execute. So far, so good!!My application is to power my sump pump intermittently, so-as to save wear&tear on the pump. The sump fills every hour, but only takes 1 minute to empty. This timer works perfectly for this app - and its easy. I like the display that shows where it is in the cycle.The same vendor makes another timer that also includes this infinite-loop cycling, but it has a resolution down to 1 sec (instead of 1 minute). In this way I can empty half the sump per cycle, which greatly reduces noise because in just 30 seconds the water level is still above the input.Love it!The ONLY downside I have for it, is that I can't really use the bottom outlet when I plug this into the top one. Other than that, it's greatWorked as it should. Easy to programTrès bon produit aucun problème bravovery good price and good quality.Works as intended.
