The most useful feature of this software is the sleep timer which allows me to set my computer to go into sleep mode for a certain amount of time without having to restart it. This way, I can continue working while my computer sleeps. Sometimes, however, the software doesn't work properly. Even though it says that it's working, it's still freezing at times. I also dislike how some features are hidden from the user. For example, you have to do a lot of clicking to find the settings. I would suggest using this software if you want to save energy and cut down on battery usage. I'm saving energy and am able to use my laptop all day long instead of having to constantly charge it.
