Top customer reviews
At under $20 this lock seems to be about the equivalent of the Kryptonite Evolution (which costs more than twice as much): The shank is locked on both sides rather than just one so a thief needs to cut the shank twice, not just once. The metal seems strong and quite thick although the metal isn't covered by a very thick/soft vinyl so it looks less thick than the Evo. The lock mechanism works well and the lock comes with two keys.
A lot of the negative reviews focus on the mechanism refusing to work or being difficult to operate. It's important to pre-treat a bike lock and then regularly maintain it with Lock-Eze Graphited Lock Fluid or something similar; or at least WD-40. I use Lock-Eze on all my locks as soon as I buy them and then again at the beginning and end of every cold season. The treatment keeps the lock operating smoothly and prevents water from freezing in the mechanism. It also helps to remain calm and deliberate when operating a key in a bike lock.
Other negative reviews mention the mount. I don't use the mount of this or any other lock. I use three different bikes so putting a mount on one isn't going to do me much good. Besides, it's easier to carry a lock in a pannier or backpack or just hooked onto my belt or around my shoulder, depending on the lock type. Maybe this lock's mount is terrible but it isn't necessary so it makes no difference to me.
For the price, currently under $20, this lock cannot be beat for a medium-weight u-lock. It's way better than more expensive, lighter, single-locking u-locks like the Kryptonite Series 2.
The only deduction of that star is because I had to order a different carrier bracket in order to mount it to my bike properly.
Two of these, located low on your bicycle and securing wheels and frames to immovable objects, offer an extremely cost-effective alternative to more expensive solutions.
If a competent bicycle thief really wants your bicycle, it will be very difficult to stop him.
You want to make your bicycle more work and so less appealing that the others.
Actually, when I bought this lock, I've seen the comment that this lock is notorious. However, I was addicted to the low price. And the fact proves that I'm totally wrong. Wish no one buy this inferior lock, because it may ruin you bike!!!
