This timer is installed in a commercial spa setting. Works without fail. Its been in use for several months.I purchased this unit to use as a timer to turn off an electric fence and have the timer turn it back on. Before I had this, I'd turn the fence off when someone came to the door and I'd forget to turn it back on. It works perfectly; it turns it back for me when it runs out. I had to wire it differently to have it on when the timer was on and their support was not only friendly (treated me like friend) but gave me simple no nonsense instructions on how to do it. Couldn't ask for a better unit or service. It is a bit pricey but it is also a heavy duty industrial unit, so it should out live me.Been using now for while. Work like an old Timex.Just what I needed. Got it right on time. Very fair pricewe have a apartment complex and works great until now in our Jacuzzi,just turn the switch and it is workingsome companies in Jacuzzi sell 1 fase timer , but do not use that because the blowers are 200 volt 2 fase.it will kill your Jacuzzi blower.The timer met our expectationsGreat price delivered on timeI've purchased this timer because it has both normally closed and normally open contacts. I used the normally closed to power the pumps in my fish tank. When it's feeding time, I set the timer for 5 minutes, the pump stops and the fish can eat in peace, without the food being sucked into the filter.
