### ⭐⭐⭐⭐⭐ Great product
*by M***K on August 23, 2025*

Perfect easy to install works great

### ⭐⭐⭐⭐⭐ Used to replace my T1202m1 - Works great - Easy Install
*by T***M on January 2, 2025*

My pool timer stopped turning the pump on and off as it usually does. Sounds familiar? At first I wondered if it was the trippers simply worn out on the timer and not the entire device, since I could feel the gears on the back of the dial moving with my fingers. I looked at the on and off trippers on the timer and they seemed fine so I knew it was time to replace mine, which I believe was the original of this 20 years old house. I was able to pull the device out easily and saw the T1202m1 stamped on the back of the device panel. Upon searching on Amazon, this came up and decided to try it. I did not need the gray metal box but the device simply slides out. After turning the boxes breaker off, I rewired the new device exactly as my old one was wired. You can see from the picture that they look nearly identical. Ill say that the new device didn't necessarily snap into my old panels grove perfectly, but it's stable and secure and fine. I powered it on and it's worked great. No issues and I'd say installing took 10 - 15 mins tops. I'm not an electrician, just a dad that wanted to save some money on a DIY job at home. Seems great 👍.

### ⭐⭐⭐⭐⭐ Great buy
*by M***A on August 20, 2025*

Easy install as long as you have a basic understanding of electricity. Nothing a google search couldn’t help with. Working as intended!!
