Customers say
Customers find the U-lock to be very strong, with one mentioning it secures to almost anything, and they appreciate its functionality and ease of use. The size and value for money receive positive feedback, with one customer noting it’s way cheaper than a Kryptonite lock. However, customers disagree on whether the cable is included, and while the lock is easy to use, customers find it super heavy. Additionally, the sturdiness receives mixed reviews, with customers noting the bracket is not as sturdy as expected.
