Reddit reviews Trademark Global 72-0850 Super Door Stop Alarm - Great for Traveling - As Seen on TV

You can get an app for your phone called "my security app". It allows you to send a text to your chosen contact number, and an email of your gps coordinates to them. It also allows you to take a photo of someone and send that as an email. It's also got a panic button which works like a rape alarm (flashing and lots of noise) so if something were to happen even if you're not at home it might be worth getting an app like that. If you think the creepy guy might actually try to break in, you can get personal alarms that once the pin is pulled out makes a loud noise until you put the pin back in (http://www.amazon.co.uk/Minder-Personal-Alarm-with-Torch/dp/B0019SLCBI) I used mine for my shed since I didn't live in a nice area, so you can attach it to either side of a door so if he was to break in, you'd be alerted to it, and since it's an alarm instead of a dog barking your neighbours would know something was wrong too. Another option is a doorstop alarm (http://www.amazon.co.uk/Super-Door-Stop-Alarm-Traveling/dp/B001D27YC6) Both of these are pretty good for renting because you don't have to drill holes or anything into the house, and they're also pretty inexpensive.

This one costs a penny!

This one is 5$

This is a different kind but will sound an alarm if she tries to just shove the door open, also super cheap.
