Why use an Anti-Siphon device, won't somone just drill a hole in the tank to get the fuel out?

95% of fuel theft is casual and internal and consists of regular skimming off of fuel, this usually goes un-noticed for long periods of time.  Professional theft is rare, breaking the tank to remove fuel even rarer and an extremely dangerous and messy way to steal fuel, a thief is much more likely to target a vehicle that is not fitted with an anti-theft device.

Are the devices easy to install?

These devices can be installed in approximately five minutes.  See the video by the image for fitting.   A fitting service can be offered for an additional fee.
