Excelent product
Excellent lock, very secure and easy to use Review: This lock exceeded my expectations. It is sturdy, easy to install, and the alarm is very loud, which is perfect for deterring any theft attempts. The materials feel high-quality and the mechanism works smoothly. I've been using it daily and have had no issues so far. Great value for the price. Highly recommended for keeping your motorcycle safe!

Loud
Very very loud alarm. It does what it says and I like that it gives a warning before going off. The only thing I don't like is that it is very difficult to get the key in and sometimes the alarm goes off while I'm doing so. I have not tested if it's waterproof yet, but it's very sturdy and doesn't break when I drop it. It looks well made and changing the battery doesn't look too complex.

Effectฤฑve!!!
This is not a lock you cannot cut or break, but it will wake up the whole neighborhood for the time it takes to cut this. It is loud, but it also has a kind of wavelength that drills into your brain. Hard to bear the alarm. It is also very sensitive. It is attached to the front wheel, but it will warn you even if you touch the back wheel! I feel my bike is well protected with this, plus other measures that I already had in place.

Great Value Disc Lock with Loud Alarm and Useful Reminder Cable
This is a great-priced disc lock for motorcycles or scooters. Itโs easy to use, locks securely, and comes with a loud 110 dB alarm that goes off if the bike is moved โ a great deterrent. The set also includes an extra battery and a bright reminder cable (like a plastic rope), so you donโt forget the lock is on your disc. The key is simple and works smoothly, though it might not be the most high-security key design. Itโs possible it could be easier to duplicate than more advanced locks, so I wouldnโt rely on it as your only layer of protection. That said, for the price, itโs an excellent secondary lock to have. Compact, waterproof, and comes with a carry pouch โ definitely worth it for peace of mind.

Good functional motion sensing lock
I like this bike lock/alarm so far. Comes with extra batteries and a plastic coiled reminder cord. I use it to secure my foldable ebike. Alarm is plenty loud enough for me. I don't think it's too sensitive either. I accidentally set it off one time when I was removing my ebike from a bike rack and forgot to remove the alarm. I use it with sturdier bike lock. I don't park my ebike outside overnight and when I'm out and about on my ebike I don't usually leave it parked in public spaces for very long. I do like the extra piece of mind that comes with using it. Let's face it, there's no way to make a bike completely secure in a public place. The best you can do is make thieves consider easier targets to steal if they come across your alarmed and locked bike. I picked a red color because I wanted the alarm to be noticed and the orange reminder cord also helps. It comes with bag with a Velcro strap so you can attach the alarm to your bike frame when not in use

Best low price security system
Extremely loud! Reliable! I clipped it on my moped because theives stole it last time (thank God for built in GPS tracking I was able to get it back) and I feel more at ease ๐๐ผ Tested it out and man does it ever hurt your ears. Piercing sound. Should wake up the whole neighborhood. Will update how long the battery lasts. So far so good.
