This is an actual review from an actual purchaser of the product. At the time of this writing, all the reviews were from people that either received the product for free (26 reviewers) or were not marked by Amazon as actual purchases (5 reviews).If you are looking for an inexpensive lock to secure an inexpensive item, I do not want to dissuade you from considering this lock. I have kept my purchase. Someone put quite a bit of work into the making of this lock, and more expensive locks can be defeated anyway. The questions are: how much do you want to pay for the higher protection level of a more expensive lock, since nearly all locks are mainly just time deterrents, and what is that time differential. Often, just having a lock is enough of a deterent.If you need to secure an expensive item, however, you may want to know the following:1. The 15.00mm measured bar thickness shown in one of the advertised images is actually between 13.50 and 13.70mm on the lock I received. That measurement includes the coating thickness of approximately 1.835mm x 2.2. Unlike many U-locks, the base that caps the U-bar hinges at the end opposite the key lock and remains attached. When the U-lock is fully open, a portion of that base rotates into the U-bar's 3.9 inch opening [3.8 at the top], causing the actual usable opening to be around 3.3 inches. If you are hoping to use this lock for a 4 inch tire, like I was before I received the product, look elsewhere.3. The hinge I mentioned above appears to be a pin and is actually slightly visible. I'm unable to measure its thickness without destroying the lock, but it appears to be just a few millimeters of material at best, maybe around 2 to 3 -- nowhere near the thickness of the U-bar. That tiny little pin is what secures the U-bar to the base on the end opposite the key hole. It is not secured by the full thickness of the U-bar seen elsewhere.4. The end of the base opposite the lock, where the hinge resides, is always wide open.The security level of this U-lock is lower due to #3 and #4, but I've given it 3 stars overall, as the lock is still a deterrent.

The lock is incredibly sturdy, with a sturdy build that feels reassuringly heavy in the hand. The 6-inch length is perfect for securing my bike to various posts and racks without any hassle. The waterproof feature is a lifesaver, especially during unexpected downpours. It ensures that the lock mechanism remains smooth and functional, no matter the weather.One of the standout features is the heavy-duty anti-theft design. Living in a bustling city, bike theft is a real concern, but this lock gives me peace of mind. The sturdy mounting bracket makes it easy to carry around, and it stays securely in place even on bumpy rides. The keys are well-made and come with a spare, which is a thoughtful touch. I've never had an issue with the lock jamming or the keys getting stuck, which is a testament to its quality.The convenience of this lock is unmatched. It's quick to use, and the locking mechanism is straightforward, making it ideal for those rushed mornings when I'm running late. The design is sleek and doesn't add unnecessary bulk to my bike, which is a plus.

This is a small, lightweight U-lock that's going to give you a moderate amount of protection for your bike or scooter. If you need to lock the wheels as well as the frame, you're going to need an additional lock. It's perfect for leaving my e-scooter outside a cafe or store for a while. It mounts on the scooter frame, locks and unlocks easily, and doesn't weight a ton.If someone wants your bike, or scooter, no lock is going to stop them, but this is a good deterrent for relatively quick stops where you don't want your stuff to walk away. For the price, I'm very happy with it.

Great value for a strong and reliable bike lock. You'd need incredibly strong cutters to remove this string steel bar and there's no hacking a combination lock when this requires a key. The manufacturer nicely offer a key and a spare.This is a quality lock and is not cheap. The price is fair for the quality and reliability. I would buy it again and again if needed. You don't want to lose your bike by making it easy to steal. I recommend this lock wholeheartedly.
