It was delivered by 1pm and installed and running by 2pm. Very easy to install. Remember to take pictures of the original so you don’t get the wiring confused, and to turn off the breakers. My timer was working, but it wouldn’t shut off. So many times we would kick it on and forget to shut it off. Having a working timer will save me money in the future. First pic is old timer box, second is the new mechanical timer installed inside old box. ### ⭐⭐⭐⭐⭐ Excellent Customer Service *by on Reviewed in the United States October 1, 2019* This is going to be an unusual review of this item. First off, I purchased this as an exact replacement of the original pool timer that was probably there since the pool was built. We bought this home from a previous owner 14 years ago and though I don't know exactly when the pool was built originally, I have every reason to believe the old part was the original timer. That says a lot about its quality and reliability. But it did ultimately stopped working.So, the new replacement came. It is literally a snap to remove the old one and install the new one (exact same model). The snap/clip that holds it in place is a one handed operation in less time that it would take to exhale and inhale a single breath. By the way, as a tip, after making sure the power is completely turned off from the breaker, take a photo of the original wiring arrangements before removing. One Philips screw driver, and off with the wires. Putting them back in took just a few minutes. The pump turned on.And this is where I pivot to customer service. There was something wrong with how the timer dial indicator was moving. The clock was running counter clockwise. I called the manufacturer's product support who advised that I return the item because it had to be defective for the clock to behave that way. I contacted Amazon thru the usual return order process (all done online). A quick response gave instructions on how and where to return it (Kohl's nearby will repack and shipped the old item for free). A replacement was expected to be shipped in a little over a week. Meanwhile, the pool pump was running and I thought I'd keep it running and will manually shut it off and back on as I had been doing the past two weeks anyhow (with the old timer).Well, lo and behold, by early evening it turned off! That led me to re-examine or re-analyze the timer dial movement. I was mistaken. I totally misread how it was moving. I thought I'd wait till the following morning to call off the shipment of the replacement item and it would confirm by morning, for sure, if the pump will automatically turn on. It id!!Early his morning I got an email from Amazon that there was good news. The replacement will get here in three days. Oh no! I didn't expect Amazon to ship the item until they got the old one back. So now, egg on my face, I went to cancel the item.This review is about two things. This timer is one solid performer. Remember it took all those many years (power outages, hurricanes, one pump change) when it finally gave up; though not entirely. The auto timer did fail but I was able to manually make it work. The manufacturer's product support was responsive (although the product turned out to be all right). Then, this proves once again that Amazon has no equal. Bravo to customer support!!! ### ⭐⭐⭐⭐⭐ Perfect! *by on Reviewed in the United States April 29, 2026* Exactly as described. Fit perfect and works great!
