On opening up the alarm to try out the batteries and the device, I had a concern. The screw seemed really cheap, as did the screw driver. I was worried about stripping the screw itself or the plastic. But I used my own Phillips screw driver and gently got that screw out to proceed to the next step of opening up the alarm box. They give you a plastic device that looks like a guitar pick and that was useless in trying to open up the alarm box. I got two slot head screw drivers and used those to wedge away at the tightly sealed plastic. I ended up chipping the plastic a bit opening up the two halves.
Next, was installing the three triple A batteries. They looked real cheap, so I threw those away and used high quality batteries I purchased separately. The batteries installed securely. Everything looked intact inside, so I put the alarm box together again to try it out.
Next, was trying to read the very, very small print instructions with my big magnifying glass. I gave up on that and went to You Tube to find instructions there and I did. So I slowly went through setting up the remote control’s three buttons. That went well and discovered, an excellent bike horn. The seven different high pitched alarm to chose from in pitch and the three different types of noise was a perfect deterrent noise.
I don’t get my new e-bike until May and can’t install/ try it out until then. But I’ll install the alarm with the tie wraps and the two-sided stickers provided. The location will be under my seat in the posterior direction to keep it drier.
Once you activate your alarm, by the remote button. The first disturbance (dependent on sensitivity setting you chose. I suggest the 4th level) your alarm sounds a warning short beep. On the SECOND disturbance of your bike, then the continued alarming begins. The noise definitely will attract onlookers and annoy your bike thief. This remote is effective for 60 feet away. My Apple Air Tag will be located under the bike seat, just inches away from this alarm - under black Gorilla Tape. The remote control will be located by my right thumb on the handle bar, because of that cool sounding horn. I use my plastic rescue whistle as well and a flicker bell alarm to warn people ahead, I am coming behind them. Then I announce verbally, “passing to your left” and carefully pass other hikers on the bike pathways.
The color black blends into my seat and bike rack color and the looks of the alarm appears esthetically good for my bike. Overall, I am confident the alarm/ horn will endure a long time and will do its job to SCARE AWAY THE THIEF or at least slow down the bike thief. Even though the bike horn will be located under my bike seat, I am again confident pedestrians and other bikers will hear this horn. So good price and apparently good, effective bike alarm!!
