  • Heavy duty, great quality
Style: 120cm/4ft x 15mm Diameter Chain with U Lock
This lock is awesome,you may want to change the lock itself. The lock seems a little flimsy but definitely does the job. The chain itself makes this worth the money

  • Heavy duty
Style: 120cm/4ft x 15mm Diameter Chain with U Lock
So far it's been a good chain and lock. I think just the sight of it deters would be theives. It's very durable, and good length that I can lock up to almost any bike rack or post. Really heavy but good secuity.

  • good chain
It's thick and sturdy. Feels very secure. Heavy, but not too heavy to carry in your backpack if you have a healthy back. I wish it was longer as it's hard to wrap it around the bike and a thick object like a tree as well. Nearly impossible. Have to chain it to something much thinner like a pole

  • Chain is fantastic. Lock could be a little tougher to match chain
Style: 150cm/5ft x 12mm Diameter Chain with U Lock
This chain is a BEAST but that lock could be broken with a sledgehammer fairly easily if you can't hide it behind something. I got two to lock down my very expensive generator and I've got the locks buried so they can't be easily accessed. Other than that, this is a fantastic chain and would take some major equipment to destroy. I would def buy again ... show more

Big ole deterrent, match it up with another lock and make thieving difficult and time consuming.

  • Cheap, shoddy lock, bad welding.
Style: 150cm/5ft x 15mm Diameter Chain with U Lock
I seldom leave bad reviews but feel it's important here. This is crap. The body of the lock is made either from plastic or from some really cheap pot metal. I can't imagine it surviving one blow with a hammer, and the key action is sticky and unreliable. The chain is heavy, but the welding of the links is extremely crude, which leads me to think that the steel is of low quality here, too, but I can't tell for sure. A clue that I should have paid more attention to: there are other identical products sold under different names on Amazon, also very inexpensive. No matter the product, that'a usually a predictor of generic low-quality items. ... show more

  • What I expected
Great alternative to that other brand I know you're looking at. I use this for garage security so it's not at all open to the public. No, theft hasn't been attempted so I can't say the durability as far as being tested in a real life theft scenario. However, this thing is beefy. No joke. If you're looking for a sinch chain to get a long distance without a full length of chain, this is it. They do come in different lengths and thicknesses so be sure you know what you're getting. 12-13mm is quite beefy. 10mm is probably the minimum you want for a chain for bike security. ... show more
