Review on PerfecTech Simulated Anti Theft Flashing Security by Michael Willis

Wanted to see if they have this deceptive effect and it closely resembles the blue flash of my real car alarm. Easy to Use - There is a small switch on the side to turn the flash on and off. According to the instructions, even if the switch is set to "ON", the device does not flash in broad daylight, but in the dark. Shortly after taking it out of the box, I attached it to my dash in just 25 minutes in the sun. exposure, and it blinked all night. It seems to blink about every 8 seconds to save battery. ________________ Update December 16, 2017 Ok, 6 months in use. How are you? flashing shorter and shorter even in full sunlight. Temperatures fluctuated between 72 and 80 during the day and never came close to freezing at night. I did the last test today. I've left the unit in the sun for less than 6-8 hours over the past 8 days to see if it can charge to flash like the day I bought it. During charging, the switch has been set to the OFF position to avoid wasting energy. After I brought it inside, it flared up brightly for about 4 minutes and then was dead.
