Lidatek one transponder may work well if the car is not big and the color is not too light, I was impressed with the results from the AL6 but the problem with the Antilaser is that its transponder is way to big to camouflage it and hide it from view on the rear of the car, since here jammers are ilegal and they must be reasonalble disguised. This may be the problem with the DriveSmart as well from the pictures I have seen. Thats why the Lidatek has one great advantage over the rest of jammers here.
