When it arrived I was pleasantly surprised. The alarm unit is fairly robust, easy to fit and set-up. It is smaller than I imagined which is a positive. The remote is very solid, the buttons have a quality feel and the blue led ring around the "arming" button along with the chrome bits just set it off. Detection is impressive and wow is that sounder loud! Peace of mind at a great price.

Thanks. **Q: I use this on my kayak- it is on the car in the driveway overnight when I leave early. I would like extra remotes, one in the car,one in the house.** A: Thank you for purchasing and asking questions. The additional remote control link is this: https://www.amazon.com/dp/B084VTYF51 **Q: I have an electric car. Could I put this in the trunk, set at it lowest level of sensitivity, and use the remote to sound it to alert a pedestrian?** A: You can have it in the "off" setting. The remote has a button that will work as an "alert buzzer" even when the alarm is off. The lowest sensitivity setting would be triggered from a moving car if you had it armed. Just leave it off--or un-armed--and you can use the alert button if you need to make a sound with it. It's very loud & noticeable. ~JSV ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth every penny. *by T***D on 5 August 2023* After reading about the remote control in other reviews I was a little hesitant about buying one, then I saw this "upgraded" version.
