It is cheap but does the job! I usually leave my bike inside a private bike gate at work, so I use the cable just to discourage anyone who intends to steal. I do not recommend this cable if you want to lock your bike in a large tree, for example, since it is 4-feet long (aprox. 1m) and the coil is very resistant to be unfolded. Also, I do not recommend it for leaving your bike outside during the night since the locker by itself (the part with the code number) seems fragile enough to be broken with tools. Finally, the cable comes with the code, so if you forget it, you will not be able to change it for an easier one.

Product is of good quality, compact and easy to use. there will be a aluminum tag with 4 digits on it that will be your combination. YOU CANNOT SET YOUR OWN COMBINATION, which I am fine with. I would not recommend this lock for anyone would has to leave his/her bike outside for an extended period of time (couple of hours), because it is quite thin (comparable to a well made ethernet cable), so it's very easy to cut. I have an office so my bike usually sits there.

verdit: economical, compact, very good for only 5 bucks. do not recommend if you have to leave your bike out for a long time.

This lock lasted less than a week before my bike was stolen. The thief broke the lock at the "key" insert. From the fracture, it's easy to see that the material used was very brittle. Save your bike and time. Get a meaty u-lock. My bike was not worth much so I took a chance and now I feel like a fool.

For $5 you get exactly what you'd expect. It is a combination lock so you don't need a key, but there's no ability to change the combo. It is a relatively short length, but they don't hide it as 4ft. It does coil very tightly, but anyone who complains about that (a lot of reviews I read) are likey too weak to even be on a bike and ignore the fact that if it did not coil tightly it would be hanging all over your bike and likely become a safety hazard.

It is not the thickest and most secure chain in the world, but it does the job.

As stated above, you can't beat the price for the item you receive as the cheapest you can even find a lock for at a Target or Walmart is $15.

For people complaining about how their bike got stolen are a bunch of idiots. What did they expect for $5? I got this lock for burning man. Mostly to deter high/drunk idiots and it's worked out perfectly in the past. I decided to buy more of these for my camp this year. I agree it's cheap. Use it to lock a shed or for the Playa. Not as an actual bike lock. It fits my needs perfectly and is inexpensive.

This lock arrived and I was disappointed to say the least. The locking mechanism is plastic and can easily be broken. You cannot change the combination on the lock either. I would not feel any security at all using it, so I will not use it just a waste of money.

It is not advertised on this item that the combination comes preset and you cannot change it!

For $5-6, I guess it's a trade off, but I bought multiple and how am I going to keep track of the combinations?

If it had been advertised as being preset and unchangeable, I would have moved along to another option.
