Looks OK. Problem with all alarms is that people don't really notice them, especially if they go off a lot for the wrong reason (say when a lorry goes past or another cyclist bumps their bike into yours whilst getting in or out of the racks). This one has a movement sensor which get tripped all the time like this.
Now what would be a LOT better is an electric shock one, that you could disarm remotely when you need to touch it. Now we're getting somewhere.
