  • Heavy duty, great quality
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

  • LOCK IS PLASTIC
Style: 150cm/5ft x 12mm Diameter Chain with U Lock
A good chain, I am happy with it. DO NOT BUY THE LOCK, IT IS PLASTIC. If you use the lock, this chain is pointless and wont protect anything. There is a cheaper option to buy just the chain from the same seller, get that one. 4 stars for chain, 0 stars for scam lock.

  • Heaviest chain I've personally ever felt!
Style: 150cm/5ft x 15mm Diameter Chain with U Lock
The heaviest chain I've ever felt. Definitely makes me feel like my belongings are behind the best security locked with this. It's the perfect length to reinforce my security cage.

  • 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
