Every House Needs at Least 1!
I COULD use 1 instead of having 3 stationed around the house but the convenience of being able to leave on the appropriate setting and have it where I need it is awesome. I never have to worry about having left something on or the phone charger just draining energy. My dad uses one for his phone (3 hours while sleeping) and boyfriend for his humidifier (6 hours while sleeping). Great little product and I have been unable to find in any stores!
These use so much vampire power. Cell phone chargers use power all the time even if the phone isn’t attached. Plug it in, select the time, hit the button. Simple!
It beats unplugging and re-plugging things if you’re concerned about saving a little on your electric bill. Just flick the switch when you need it and flick it off when you don’t.
I use it with an office electric heater to make sure it turns off after several hours as I have to often forgot to turn it off at night just to have the heat run unnecessarily. It is very compact and just requires a push of a button to turn my heater on and then turn it off in the set time.
It works perfect because half an hour later, their reading lamps go off automatically and I don’t have to worry that the lights are on all night.
I notice that someone else wished that the light on the switch would be on when this was switched off. I beg to differ: the way it is, I can easily see when I’ve inadvertently left something turned on.
Instead of always keeping the device plugged in or unplugging it every time, just flip the switch. It will help save electricity and prevent the connectors on the devices from wearing out by unplugging and plugging.
The only thing I wish was that it would offer a 9 hour option, it only gives us half hour, 3 hours, and 6 hours… just would be super if I could get it with 9 hour option too! But overall, I love the device, I have several of them now.
The settings are super easy to use and simple. It would be nice to have more time options but I don’t mind. My only complaint is That if you want to turn the device off before the time expires, you must unplug the entire unit and plug it back in.
Another great use I have found is a auto shutoff for those new electric wax warmers. Save the sent of the wax and power! 
This saves you from having to reach behind that dresser over and over by just hitting the side of the outlet. We use it for our bedroom tv as we rarely use this time, the outlet is easy to reach but if the cord was pulled each time we would be reaching and searching for the cord. Also makes thing like laptop chargers easier to deal with. Well worth it.
