Question: I need a heavy duty timer that I can turn on manually daily at random times and easily set to shut off in an hour.  Is this the device for me
Document: I've been using this heavy duty appliance timer for the last six months to automatically turn my space heater on and off to save on electricity. If find it very user friendly and incredibly flexible. When I am traveling for an extended time I'll use it as a lamp timer instead. The ability to easily set multiple on/off increments makes it very versatile and superior to some other options on the market.
I bought this sylvania 15 amp heavy duty appliance timer to use with my water distiller based on other reviewers recommendations. I'm so happy I did. It allows the distiller to turn off before residue can cook on the bottom. It was very easy to set this timer and the time mechanism seems to be precise and accurate.
Simple device, works as described. We've used this timer to turn on a dual tube garage light style fluorescent lamp for 16 hours a day for the last 2 months. The timer was easy to set up and as far as I can tell has performed perfectly. I like that there is a cover over the dial to reduce the risk of accidentally modifying its on/off times.
I like this timer because of the cover. Nothing accidently bumping it and messing up the timing. It's heavy duty. I've been using it with a space heater and a dehumidifier in my basement for a long time now and it never seems like its over heating like some other do. If I need another one I will get this one again.
I love this timer. 15 amps so it's heavy duty, it's also very easy to set up and there are no pins to lose. Highly recommended product.
I really like this timer. I use it to turn my space heater on and off. I like that it has an easily-accessible switch to turn it to manual &#34;on&#34; for when I want it to be warm outside of usual times.
I purchased three of these timers. One was a gift for my sister. Two of the three didn't work so I gave the one working timer to my sister. I'll be returning the other two. I am very disappointed as I thought the brand Sylvania would be a good one. I was only trying to turn on a light at night before I got home. So much for heavy duty.
I purchased this timer for my AC. I have a dog and I do not like having my AC run all day long during those hot summer months. Instead, I used the timer so the AC would turn on during the hottest hours of the day. It works great with window AC's! Easy to operate and change times you would like to have your electronic device operate!
They were easy to set and you can have the timer come on and off multiple times throughout the day if that is what you're in need of.
It's got to work as designed or it's useless.I bought this timer to start an espresso machine rated lower than the power rating for this device. Despite starting on time over an hour ago, my coffee maker was not getting up to temperature because the timer clicks off and then clicks back on again. This isn't a problem with the outlet the timer is plugged into.
Answer: yes
