I had one in Korea to avoid the speed cameras. In Korea, the police don't wanna hear the no front plate stuff...1 million won fine (~$850). It worked brilliantly! Pull up near some police or park the car? Bam! You have a front plate. Start driving? BAM! No plate. Going 160km/h through a 80km/hr speed camera? No Problem
The bad thing is that this lasted about a month before something mangled it. This definitely paid for itself (in Korea) but not worth it for TX. This will not last long at all if your car is dropped.
It was pretty neat!
