I don’t even use the alarm anymore because it was so loud. That’s a good thing I just didn’t care anymore. I recommend this one

When a thief wants your bike or scooter no lock is going to protect it. This when you mess with it sends a warning and then the siren. That's what you want You want the thief to be noticed a little worried and leave. Again if a thief wants your bike they're going to take it even with the kryptonite lock. A couple bad reviews on here talk about it got wet anymore work not salt water resistant, duh it's a bike lock you'll have to replace the battery at some point but the peace of mind is worth itYou can just throw this on the tires and it makes such a loud noise that if it doesn't scare the Thief away, you'll be able to run out and catch the person and subdue them for the police or your G-froends to punish.Loud AF. Make sure it only beeps once or it's not armed

Je vais utiliser ce produit pour sécuriser mon vélo contre les voleurs. Je l'ai pas encore mon nouveau bicycle, il est réservé au magasin. Je crois bien ce produit est bon, j'ai vu sur YouTube le fonctionnement de ce cadenas.

NOT WHEATHER PROOF! worked till it rained. Barely had it 6 weeks. Will not buy again. Rip off. I feel like there is a better design for the battery compartment. The screw is small and awkward putting back in. Drop and pray is the best starting method. The width of the u-bolt is smaller than I expected. Will not go around a 4" wide tire. Alarm is loud and very easy to set off. Starts quiet 4 beeps. If you play with it you can lock it without the alarm being set. Havent quite figured that out yet exactly but if u do and u want to arm the alarm simply unlock and lock again. If U hear a tone similar to a car alarm locking it is locked/unlocked as with car 2 different sounds. Double=locked and armed. May play with it tomorrow to figure out how to lock without arming so I can use the attachment piece and ride without the key in the lock in a halfway position. The locking post protrudes on both sides of the u bolt I wouldn't trust in high crime areas if ur outside of hearing range.

Purchased the lock for the wrought iron driveway gate due to curious people driving onto our property to look at our house and access the pier numerous times. Hoped that the audible alarm would discourage these unexpected visitors and allay the worries of our friendly neighbors.The alarm itself was easy to operate and appear sturdy with the possible exception of the orange tip. The lock came with 3-keys, bike mount, and instructions. Instructions were a little too basic but adequate. 3-keys were nice bonus.I wish the alarm were a bit louder but probably adequate and hasn’t disturbed my neighbors. No precipitation in over a month so can’t provide insight on its ability to endure the weather and too early to see how it handles the waterfront environment.Customer service has been excellent. Communication was very quick. The shipping was less than half the expected duration. Unfortunately, I was initially sent the incorrect lock but they quickly remedied the mistake.

Imagine a fire alarm going off a few feet away; that's how loud the alarm is. Figuring out the lock mechanism takes a bit of practice, so try it at home before taking it out in public. The lock itself is quite heavy-duty (2 lb, 11 oz), but the alarm is a nice bit of added added deterrence. Definitely a good buy.

La electrónica pésima, a la primera lluvia ya empezó a no conectar la alarma y al mes de uso no abre el candado, ha quedado eternamente cerrado, por suerte no fue puesto en mi moto. Pésimo!!

As far as the U-lock goes it at least is anti-shim, but other than that it is just as bad as your basic Walmart U-lock, albeit a bit thicker. It would only take 1 cut with an angle grinder, as there is no mechanism to lock both sides of the shackle (meaning it can freely rotate once cut).The alarm feature I'm not impressed with. I like the simplicity: no buttons or passcodes. But it is merely a simple vibration alarm. Something there's loads of cheap ones on Amazon. The electronics are also encased in a simple plastic enclosure that would be drillable from the outside in mere seconds to disable. I expect better for $40.I will probably be sending mine back .

I love the idea of the lock but I returned it thinking it was defective. It wasn't. Silly me. I didn't take the plastic off of the battery and that's why the alarm didn't work. I had to buy it from another popular selling site where I was able to speak directly to the seller. He was amazing! Amazon was horrible at dealing with my problem. He sent me a video of what I did wrong and promptly sent me a new Crystal Vision Alarm U Lock. The alarm is loud and easy to set. I apologize to the seller for my mistake in thinking there was something wrong with the lock. Thank you so much for your personal attention to this matter and for going above and beyond in making me a happy customer. I am very happy with my lock.
