Review on Motorcycle Motorbike Security Waterproof Reminder Car & Vehicle Electronics by Jonathan Unruh

They're all pretty much the same, so just go with the cheaper one. It's quite noisy and made of metal, so it seems to be of good quality. it had a warning chirp first and then just an alarm when movement continues but doesn't. it starts to chirp with every movement and then immediately sounds an alarm even when the movement stops. in addition to a loud beep (and when you approach it, it is very loud and can hurt your ears), it also interferes with driving.
