## Customer Reviews

### ⭐⭐⭐⭐⭐ Now along with a Kryptonite U lock and the heavy chain combo lock I can finally feel comfortable away from my machine
*by C***R on November 20, 2017*

Every once in a while you find something on Amazon that surprises you with the quality and the value of the item. This is that item. I didn't expect much when I ordered it but I was desperate. I had just purchased my dream bike and I was not about to lose it to some low life, piece of %$*@, bike thief. Now along with a Kryptonite U lock and the heavy chain combo lock I can finally feel comfortable away from my machine. The folks at K&K International Co. Ltd really put some thought into this little engineered marvel. It simply works perfectly every single time you set it. Extremely simple to install, I had to modify mine just a bit to make it fit on my tadpole recumbent and am I glad I took the time. For less than $25 you get a very high quality tail light, a remote and an alarm that I am sure would cost you $150 if you could find one! The alarm is the perfect loudness, a not so bad sound effect and a warning sound that helps a lot if you park it in a windy situation or crowded bike rack that could be unknowingly bumped by someone. If you bump it it chirps at you, if you continue to mess with it the main alarm goes off. The sensitivity is set to perfection, the remote works so well and is so convenient I am just amazed. This is the one to buy, a can't miss and under $25?! Buy this one and start sleeping at night knowing your expensive machine is safe. Thanks K&K for this superb device!

### ⭐⭐⭐⭐⭐ Great theft deterrent.
*by T***L on January 9, 2021*

Very happy with this purchase. Functions as promised. Alarm is very sensitive and extremely loud. Under seat mounting was a bit difficult, but quick removal by thieves would prove difficult as well. They do include a post mount as if you need a simpler option. Light is bright and horn is effective with 3 different sound options. Overall great product.Update: purchased again for new bicycle.Pros: Upgraded model has new features including more horn sounds, adjustable volume and alarm sensitivity and light sensing feature that will automatically turn on tail light at night when bike is in motion .Con: New model uses thumbscrew instead of allen screw to secure light to mounting bracket making it easier to remove. I prefer the more secure allen screw.

### ⭐⭐⭐⭐⭐ Excellent Product
*by C***S on January 22, 2024*

It was difficult to attach at first, but fortunately the second alternative (the "third time") was the charm, and it was easy. This light/alarm is an incredible buy, maybe the best in all of my Amazon purchases. The alarm is a loud 115 decibels (just shy, I think the product info related, of the noise required to cause permanent hearing damage, and I believe it), but it is not so sensitive that it goes off unless someone is definitely messing with your bike (in my case, an expensive ebike). And everything works, even the motion-sensor brake light! For 20-or-so bucks, this alarm is a steal!
