Blue Charm Fake Car Alarm, 2 Year Continuous Usage Battery Life, Red Blinking LED Light with Pre-Wired Battery Holder, (2xAA Batteries not Included)

I previously tried the other products that supposedly are solar powered but both of them failed within one week. Charging by plugging them into computer brought them back to life for a week, but then they died again. I was skeptical of their design anyways, since leaving them in the hot sun in a car to charge does not sound like a good strategy for long life of a plastic electronic item. Lesson learned.On the other hand, I really like this Blue Charm blinking LED. The battery life is an amazing 2 years. That's perfect for me since I want to put it in place, turn it on, and then forget about it. I don't have time to worry about turning these things on and off each day. No doubt, the one night I forget to turn it on, my car will get broken into!I like the design of this product also. Having the LED on a wire gave me more flexibility in how and where to mount it. Eventually, I decided not to drill a hole in my car's dashboard. Instead, I just used the double back tape to position the LED just below the dashboard but sticking out far enough to barely be seen. During the day, I can hardly notice it, but at night it is plenty bright to scare away potential thieves.I am going to order two more of these right away. One for my boat and one for my motorcycle. For the boat, I will definitely mount it through a hole in the dash. The double back tape should hold the LED in place nicely, and I will then tuck the battery pack up behind the dash also. Have not decided yet how to mount it on my motorcycle, but I am thinking to put it under the tank, out of direct sight, then let the LED flash be seen indirectly as it lights the ground underneath. I think this will look clean and also be enough of a deterrent. I might also get one for my garage and put it inside the window on the top edge of the trim. Should work well there too.Overall, 5 stars for this one!

I was installing this and a wire came off.. then I tried to repair it and the other wire came off. Probably just a defective unit .. The seller contacted me and refunded my money. I ordered another unit to give it another try.

This isn't going to make it impossible for someone to steal your car, but it may deter them as long as you install it in an appropriate area.I've left this on for a LONG time and it's still blinking as I type this. And then once it stops, all you have to do is put in new batteries and you're good.I only have a few problems with this product:1. The size. Obviously the battery compartment has to be big enough to fit batteries so that's understandable. But the part that you want to conceal to make this look legit, the light, is almost impossible to hide well. The bulb sits on this big square motherboard so it's hard to find a place to put it. I still haven't found the ideal spot to keep the light visible while hiding the motherboard.2. The length of the wire. Anywhere you can manage to dige the light will quickly be ruined by the dangling battery pack. I definitely would recommend splicing these into a longer piece of wire so that you can route the wire and tick the battery pack somewhere accessible yet discreet (and you can install a switch to the negative wire if you want)3. The gauge of the wires. The wires are so thin. I actually ended up breaking one of the wires off the motherboard by accident when I was trying to add more length to the wires and had to solder it back on. So be extra careful with this is you're not familiar with that kind of stuff or you might break it.But overall worth the couple dollars you're spending. Obviously an actual security system is better, but this cheap and easy deterrent is a good way to make it look legit in the meantime until you get a real security system.

I was hesitant on this purchase cause of the bad reviews but I'm glad I bought it. It has lasted in my hot car for 3 months straight being on 24/7 all on one battery to! The adhesive fell of but I ended up just using duct tape to hold it on my car. I also bought a fake alarm sticker to put on the windows to make it more believable.

Would buy again if needed for the price , but would buy better if could afford to.

Great device. Easy to use and I don't have to build it myself. Nice bright red LED.

Day 1: So pleased to install batteries & see brilliant RED LIGHT illumination however, I must post a “Buyer Beware!” First, for the money, no big deal! When I first opened, I saw several RED FLAGS immediately that would result in my poor experience. First, I RARELY write reviews! As a consumer, I do read these appreciate others taking the time just the same. ISSUE: Worked for just 15 Minutes before the wires came loose! The BACK PANEL is a computer board 100% unprotected with a “dot of glue” to affix TWO WIRES to mother board for it to light up. BOTH WIRES came LOOSE while positioning carefully on dashboard! I personally exercised extreme caution due to the wires being MUCH TOO SHORT to perform a proper installation. I am returning & DO NOT recommend purchasing unless you are a mechanical engineer with time on your hands to improve how this mother board is designed! I will edit post with photos in short time. Disappointed that Original PHOTOS were misleading & did not include a photo how the “BACKSIDE” of this device exposes its circuitry & glued wires. Talk about poor Aesthetics?? No way to hide it & No luxury car would have it. In other words, you get what you pay for! If manufacturer spent a little MORE TIME & ATTENTION to some details that matter the most, this unit would be AWSOME! Sorry it didn’t work & failed on DAY 1.

This is absolutely perfect for our needs. The light is bright and can be seen clearly, even in the daytime.I need a bunch more, but since we have to take out loans to get groceries and gas these days, the cost is a bit high for us.Update: been working perfectly for a year now. Still very happy with it!
