Question: Can you use a battery backup with this timer so it keeps time during power outages?
Document: Same timer I use all the time for simple on / off  use. You can swap out guts without removing metal case from wall.
Works great for my swimming pool motor/pump.Keeps great time and is weather proof.I would highly recommend it for any timing needs
I use these timers to operate lights on my farm.This is a great product at a very reasonable price. I would recommend it to anyone who need a programmable timer.
Trippers fall off the dial. Can't get them to stick to the right time. Any Walmart timer is better, as we have discovered. Don't buy this kind of defective product.
)Bottom Line; It is always wiser to pay a few dollars more and get a time-proven timer than a cheap plastic model that will never last as long due to the materials they are made of!
Can't judge the quality of the timer as I was never able to use it. When I purchased, the item name nor the description indicated it was for indoor use only. The item name has now been updated since my returning the item.
Very misleading, not only the description but on the product it list 240V or 120V. The 120V clock has to be changed out if you want to use the clock, duh that's what a timer is for. The timer is high quality but they should take 240V completely off the box and the timer on this product.
I use this timer to turn on and off my summer lights in the back yard and I have a lot of lights so I needed a heavy duty timer. This one works like a dream. You do need someone to hook up a plug in for it.
This is the same timer commercail properties use for their neon signs. I just replaced the one in my home according to the manufacturing date it lasted 42 years. The new unit same as the old one, hard to find that quality today in anything.
I had an outdoor timer that ran the front house lights that bit the dust. I went online, and found the exact replacement (that's why I love Amazon). Even though this timer is for indoor use, I just installed it in the existing outdoor box, and problem solved.
Answer: yes
