These timers haven't for years changed much in 50 years. Still work well for years and easy to set up

If the mechanism in your T103 timer breaks, this is the cheapest and easiest remedy, whether you want to replace the whole box or just what's inside. It is an exact replacement, so it is possible to save yourself a lot of time by simply removing the mechanism from the new unit and replacing the broken one (as opposed to pulling out the entire box, which is likely nailed to studs and not easy to remove, not to mention having to fish all the wires). Yes, you will have an extra box if you do this, but I'd rather have the extra box than pay $20 more for just the mechanism. In short, this unit works fine regardless of how you choose to approach it, and is the least expensive option.

I had an electrician install this for me since I don't do hard wiring. It was pretty basic since it was replacing an existing Intermatic 4-5" square timer that I had had for 30 years at least. Bad reviews on the current exact replacements so went with this. Installer had no problem at all getting the wiring done easily. It's located inside my garage to operate my front porch lights. Unless it quits on me prematurely, I give it a 4 out of 5 stars so I have some wiggle room. In less than a week of operation, however, it's doing what it's supposed to do, at the time it's supposed to do it. Directions seem fairly straightforward and I reviewed them before the electrician left and everything worked accordingly.

I've used this series of timers for over 20 years, both in-and-outdoors. The latest purchase is to replace a Compool pool automation system. I have a bunch of eperience with laboratory automation and I cannot get that POS to funstion properly. The pool service guys know nothing. So my habit has been when household "automation" is too expensive to upgrade, I swap-in these timers. They run a 250 gal. aquarium. They run all my outdoor lights (120v, NOT low voltage) and now they will control the pool. If I need some automation, I just have these run a raspberry pi or even just a few relays. I have never had a failure due to the timers. My sense is people are using these boxes outdoors as-is. Either buy the weatherproof version, or being cheap I will put the pool timers in one large weathproof box which simplifies mounting and wiring. The accuracy of the timer is more than adequate for anything in the house. The big box stores in my area no longer carry Intermatic and the replacement is junque.

This is a sturdy timer that we use to turn outdoor lights on and off around our country property. This device was easy to install, easy to set, and is quiet and reliable. Recommend.

I had an Intermatic timer that was 30 years old. It had some advanced wiring to it. I was able to swap out the timer from the old box and using the same shell put in a new timer . This left only simple wiring to connect the timer back into working order. Saved me a lot of time. Very happy with this product.

As expected it did the job-- replacing a similar model over 10 years old.
