The timer is very nice in that it adjustes to the season (dusk / dawn settings), and you can have lights come on automatically instead of having to turn them on. The draw back to this product is that it is a little difficult to program, and without the instructions it is almost impossible. Please make sure to store your original programming instructions in a safe place for future use. Other than the programming concerns, this is a nice time that does a very nice job with my low voltage lighting.

Rated 4.0 out of 5.0 by XRAF I bought another one
This the second timer of this model that I've purchased. The first one was to replace an earlier Intermatic model that had given up the ghost. This new model has been working so well that I decided to invest in another one. I use them to turn indoor lamps on and off and what I like about this model is that it automatically adjusts for the daily sunset times, so there's no need to periodically reset (it as was a necessity with the old model). I have set the 'off' time at a specific time and it turns off exactly then. It can also be set up for varying sunrise times, although I personally don't use that feature.Yes, it's a little complicated to do the initial set-up...I had to clear it out and start again a couple of times, but it can be done with a little patience. Four stars...it would be five if the set-up was less complicated.

Rated 5.0 out of 5.0 by yota87truck Great Product!
I am very happy with this purchase. For years I have been dealing with manual click timers and combining them with a photo cell. These work great to install in a lighting transformer. I know that at dusk and dawn it will turn on/off where as with a photo cell there are so many unknown variables.

Rated 3.0 out of 5.0 by spencerpdx Works as intended but no manual override
Relatively easy to program, works as intended. However, there does not seem to be an override feature; I have a floor lamp connected to it, and there is no way to manually turn the floor lamp on or off without unplugging it and plugging it into a different outlet. Also, the product was shipped to us defective; I had to take apart the battery and put it back in for it to properly function. After doing that it worked, though.

Rated 5.0 out of 5.0 by David Intermatic Timer battery back up device
This timer with a battery back up. This device is good when there is an outage, but the clock and the timer set will not be messed up compared to other devices which don't have.

The programming instructions are clear & concise. This timer works exactly as I expected; including the override feature that I wanted. The programming was the easiest of any similar product that I have previously owned. The knob makes programming very easy!
I really do not understand any of these negative comments by others; I have had no problems with the DT 620, and would recommend it to everyone who wants an easy to program timer and one with a feature that allows the user to override the program without deleting or disabling the program.

Rated 4.0 out of 5.0 by DeltaRotal Versatile timer, great for eb and flow.
Timer works great for multiple every day usage. Can also be set for alternating days or sunrise/sunset. This is my go to timer for accuracy and dependability. Only downfall is the spinning nob, used for adjusting just about everything, begins sticking after about a year and numbers begin jumping all over the place. A little faness and patience and you can overcome this issue.

Rated 3.0 out of 5.0 by Seamus DON'T LOSE THE INSTRUCTIONS!
The biggest challenge is programming - it's not intuitive. If you lose the instructions, you're hosed. I use it for Christmas lights. Each year, I need the instructions because the programming procedures are so stupid. It's not one where if you've done it once, you'll remember it. When it's set correctly, it works fine. But getting it set correctly may take a bit of trial and error. A device as simple as a timer should not require instructions to be regularly referenced.
