Great price and works well! Easy to use, and the alarm/siren is loud! I set it off on purpose to test it and my wife said she could hear it inside. Great value for adding a lot of piece of mind!

Great little product with high pitched piercing alarm. You can definitely hear it! Turns off with the key. Ready to use straight out of the box. Great idea to put a reminder cable on this so you don't damage your scooter or motorcycle. Its heavy, so sturdy and well constructed.

So far, it has been working excellent. This has been after 6 months of use. It's very sensitive, it has very well built in electronics. For some reason it comes with extra batteries, but there's already batteries inside. And the batteries are full strength. Easy to put on, easy to put off. I just wish that the orange cord, the reminder cord that you put on your brake handle or your throttle, would be a little bit longer. I have a Suzuki Boulevard C50 (a cruiser) and so the distance from the brake rotor to the right brake handle, is a little bit long, and it feels like I'm putting a lot of strain on the orange cord. It's just very tight (hoping it will never snap) so if they made this just 2 inches longer, that would solve the problem. That's my only input. Everything else is perfect

I love this product. It’s really cool. Plus I have ADHD and I’m liable to takeoff with the lock on the disk. The cable helps remind me not to do that. I can connect it to my throttle. It’s very sensitive gives a warning and then goes off up upon the 2nd movement sometimes it even goes off when it’s storming outside.

It feels like a good quality lock, came with two keys and extra batteries. And the alarm is loud

I've owned and used this lock for an entire riding season. Its batteries have lasted that long, and have shown no indication of running out. It's small but heavy, and my god is it sensitive. Maybe that's the only thing I dislike about it is how oversensitive it can be- if I know it'll rain, I'll make sure to put it on the back wheel instead of the front wheel, because if the rain hits it, it will go off. It's been very sturdy, and I find I don't use the cable it comes with. It's so sensitive that if you even start opening up the tail bag casually instead of carefully, it'll beep at you. I live in an area where there are people around all the time, so I use it as more of a 'pay attention to me, I'm getting stolen!!' alarm than an actual theft deterrent. When I sleep, I leave my window cracked open. If anyone touches the bike, even the neighbor's cat, it'll chirp and I'll know to listen to see if it goes into full scream-mode. The alarm itself is pretty loud and piercing. It does hurt my ears up close, and it's *very* noticeable even several hundred feet away. (Definitely wakes me up at night when it rains and I forget to move it to the sheltered brake rotor on the back wheel!) Pros: -small, easy to store -very durable -loud -battery lasts long -water and weather resistant/proof -direction of unlocking twist (clockwise) means that if you mount it right, it's easier to unlock without going off Cons: -Can be oversensitive -Goes off in the rain -lock mechanism is beginning to get a bit stiff after one year of weather-induced neglect Would I buy it again? Oh yeah, it's perfect for my use-case scenario.

Awesome theft deterrent and a must have when traveling! The device itself is extremely well made and not easy to defeat, even with an angle grinder! It would take too much time, noise and effort to defeat this device, and it’s noisy as all get out once it’s activated!!! The alarm sensitivity is excellent and triggers the moment that my bike is disturbed in any way, and the loudness will attract attention from concerned citizens I hope!?! The device comes with an extra battery pack that’s easy enough to swap out. I ordered extra batteries to keep the spare battery pack charged, loaded and ready to go. ***This device also comes with a lock reminder cord that should ALWAYS be attached when the lock is in use because I don’t want to pull off while the lock is attached to my brake rotor, that could lead to having a very bad day! I am definitely ordering a second unit as a spare or add on, and I highly recommend this device, especially when used in conjunction with other forms of theft deterrents! Unfortunately, thefts can’t be totally eliminated, but it can be slowed down, deterred or prevented effectively. Get It!!! 🏍️ 🔐 👍
