Query: Could not get up without this

I drove a truck for years and always used one of these because they are loud and driving a truck you never know when you get a chance to sleep and if it is night or day. Without having a set sleep schedule it is hard to wake up. When I stopped driving a truck and got a job with a regular schedule I took my Screaming Meanie with me. After about 10 years the battery in mine busted and ruined mine so I ordered a new one and I love it just as much. It is so loud that I can hear it outside of the house. So if you have a hard time waking up or sleep in a noisy environment this is for you
