Does this have to be set very day or can you set it and leave it for day after day use?

Its a strictly set and water each time, is not programmable. The clock is strictly a timer and you must reset (rewind) it each time you sprinkle.

It's manual like an old boiled egg timer. You have to set it every day, but it's cheap and it works.

It has to be reset every time you use it. It counts down to zero from wherever you set it. If you set it for 20 minutes it shuts off after twenty minutes. It's a great little timer for the price! I have had mine for 3 years and they're still working perfectly. I take them inside for the winter.

You have to go every time you want the water on. You can't set it up for a daily time and it goes off on its own. No.

It is just like a kitchen timer--you set it each time you use it. It is a wonderful way to save water if you don't have automatic sprinklers, which I don't. Maximum setting is 2 hours, but you can set it for unlimited use on "manual", which makes it not a timer at that point. You cannot leave them on the faucet with water in them in the winter--if the water inside freezes, it cracks. Drain it in the winter (I live in Southern California so I use mine all year).

No. Each night you set it (one button push if you're keeping the same time) to go off the next morning or whenever. If you don't want it to go off on Saturday morning, just don't push that button the night before.

You don't need to set it up daily, but when I tried to reset it for daylight savings time, it just broke. I got a refund for the clock. I found another one that was more expensive, but with higher ratings.

No you don't have to wash after each use. You'd have to let it dry fir 24 hours setter each wash so you could limit yourself to using it every other day. Some puerile buy two so they can wash every day. I would every week.

I never have left it on for days at a time, but I have left it on for a couple of days when my little dog is at the caregiver's when we've been gone for a weekend. I use mine in my chihuahua's crate for at night. I start warming it up early evening and usually turn it off mid morning the next day. I would think it would be fine to leave it on most of the time if you are using it for a pet who lays on it most of the time, day and night.

Yes it does need to be set. Should have come with instructions on how to do so.

Yes you can set different times for different days. I do that for a indoor lamp in living room now.

Personally, I've only run the unit for 24 hours straight. I cannot comment on 'several days' but I believe that it should also be fine. Also, you should note that the settings can be configured for it to turn itself on and off AUTOMATICALLY. This means that, there is no need for the unit to run CONTINUOUSLY, for several days.

If you want to turn on every day at a certain time, you can set it for any time anyday and turn off a half an hour later. This is not just an "egg" timer.

I don't believe you can specify which days like your example. If your electronic is only plugged in the device during those days, it would still provide what you want. You can also hit a single button to turn it off on days you don't want it operate... You would just have to push it every day.

I guess the answer to that is no. You can set it to be on during the day or have the light sensor will keep it off in daylight. I don't think the motion sensor it will turn it off and on in daylight. I have mine set to be off in daylight and to come on for 5 minutes at night in response to motion. If you had reason to have it turn off and on in daylight, you would probably have to cover the light sensor.

No. You can set it for frequency of 1-7 days. So you could set it to run every 3 or 4 days to meet your scenario. Hope that helps.

Yes you can. When programming, you can set each day to run a specific amount of time or completely off.

It is easy to set the alarm and once set, the alarm time is retained by the unit. However, you have to turn the alarm on every night. When you turn off the alarm in the morning, it is turned fully off and not just reset to alarm the following day.

Settings continue every day - The only time I have had to mess with the timer again is maybe once every 8 months or so because the little plastic ticks that you use to set when it turns on/off sometimes get nudged over time through the timer's design and so sometimes the light turns off later than you want... but not a huge deal

The directions say to leave it out in direct sunlight for an hour to refresh it. I would suggest it be on a very warm day and probably for longer than an hour. I don't get a lot of direct sunlight, so when I left it out I didn't notice a lot of difference.

You have to reset daily, although I have not messed with it to see if there is a setting that could be changed to make it reset daily.
