YOHOOLYOYOHOOLYO Alarm Disc Lock Motorcycle Disc Brake Lock Anti-Theft Waterproof 110 dB 7mm Pin 5ft Reminder Cable for Motorcycles Bike Scooter Carry Pouch (Black)

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

Updated Review: The seller reached out to me immediately and provided a full refund to me for this item. I must have just happened to receive a product with the slight defect noted below. However, as I mentioned below, the lock itself still works well. I respect businesses that obsess over their customers and maintain integrity. Therefore, I am adding 2 stars back (5 stars). I would recommend purchasing this product from this business if you are on the fence since you’ll be taken care of if something goes wrong.Original Review: The lock itself works fine. I have not had any issues with unlocking or locking. However, the built in alarm started getting triggered randomly. I parked in an indoor garage with no exposure to wind/movement and no direct exposure to other elements such as rain. My 30 day return window elapsed, so I was forced to resort to removing the batteries to the alarm (it is very loud and I cannot risk disturbing my neighbors if it goes off while I am gone) and so I strictly started using this as a lock, which was disappointing. I was hoping to have the alarm functionality. The issue started occurring about 60 days after purchasing. I have owned this lock less than one year as of the date of this review. I deducted 2 stars for the alarm issue. If the manufacturer or seller reaches out to resolve the issue, I will update my review accordingly.

Okay lets talk, no this is not an AI review.First off the price point attracted me. I recieved it today and it is packaged very well. You get the lock, spare set of batteries (I do wish they were not button batteries but at least they give you a second set) a nylon pouch to hold everything, a coiled lanyard, two keys, an allen key to open area to replace batteries.By the weight you can tell this is not some cheap lock. The alarm is pretty piercing and loud. The throat is pretty deep so even if your rotor doesnt have cooling holes it still can reach the cutouts so it will lock onto the rotor.Am I happy with the purchase? YES, actually I will order a second one for my second ebike. (You cant be too carefull) SIZE: takes up the room of two packs of cigaretts. Definintely with the cost as long as batteries got a decent life on them.

We love this product. We just wish that it was a little more durable as far as where the key goes In to unlock the lock itself. So we live in a residential area where there’s a lot of people so waking up early in the morning and having to try to wrestle around with the key to get it in just right after a while it’s hard to get it in and the alarm goes off and it’s very loud, which is great you know it works, but as far as the key going in so many times, it feels like it’s starting to wear, which is scary. The only way to take it off if was to get stuck would to be by replacing the whole disc brake itself on the minibike…other then those things, it’s loud and it also is very touchy. For instance, when it rains really hard, it will make it go off. The wind hasn’t seem to touch it. Only the rain has seemed to set it off.

Works flawlessly and is super loud

There are literally dozens of similar locks on Amazon and other sites and you will find something negative about all of them, but for the money, this lock is solid and does the job. I think that when looking for a lock to secure your motorcycle, it really depends on where you are parking it and how at risk you are of it being stolen. I park my motorcycle in front of our house and in front of one of our cars, so getting it out is a chore in itself. For my situation, this lock suits my needs and the bright yellow color is a deterrent in itself. The alarm is loud enough to draw attention and installation/removal is simple. The only negative thing I have to say is that I don't like how the alarm chirps as soon as the key touches it. And if you take too long to unlock it, like when it's dark, the alarm WILL go off, which is annoying. Otherwise, I like it!

We bought this to lock our scooter in the Philippines. It works great and the alarm is sensitive and perfect!
