    • 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.

Just received today. Happy with the cloth encased chain size, may need to get a better lock. On balance, it will serve its purpose.
Reviewed in the United States on March 18, 2025 by Amazon advertised that this American flag tonneau cover fit my ford f-150 but it did not. I trusted Amazon so I didn't try to install until few months later when I learned it did not fit. Now I'm out over $200.

    • 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

Punk tried to steal my bike tow nights in a row. First night hollowed out my ignition. Second night came back with large bolt cutters which failed. Caught him in the act and chased him down the street. Was buck naked when it happened otherwise I would post a pic. Thief didnt come back after a naked tattooed red neck chased him off. ... show more
