Review: Chain lock - Yeah brilliant chain and lock, very strong and easy to use. The weight is heavy so you know its strong and reliable. Definitely value for money. Only downside was that we had to oil the lock itself after all the rain last year, starting seizing up but a little WD40 and was perfect again.
Review: Strong secure bicycle lock. - Excellent bike security chain. Very heavy and feels secure. Bought one for my bike and one for my husbands when I saw the quality. Super.
