The device is smaller and lighter than I thought, but provides a surprisingly realistic simulation of light that diffuses a TV in the room. If you do not see directly through the window, really gives the impression that is in the room watching TV straight. Very positive I find the low power consumption. My parents have the unit gained after a break and were so pleased that they have bought a second one for another room. Of course, the device does not provide protection against break-ins, but has a certain deterrent effect.
Conclusion: good TV Simulator.
