  • 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

  • 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

  • Very heavy duty and needed for any bike parked outside in a sketchy area. Very heavy duty and needed for any bike parked outside in a sketchy area.
Style: 150cm/5ft x 12mm Diameter Chain with U Lock
Product is exactly as described. Works great as I am a travel nurse and haul my bike everywhere. I ride it daily, but I also need it be there in the morning. Chain is HEAVY. With hexagon shaped links. You won’t be disappointed. Depending where I am parked at night, it locks to the trailer or my truck. And the u-shape lock wraps the frame perfect. ... show more

  • 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
