Lock works but is not feasible. Operation is rather difficult as u cannot actually use ur hands to loosen the lock as it is very tight. U have to use a key or something to pry the orange bit (end) loose before u can start to lock ur bike. Also, when keeping the lock, it is extremely difficult to push the parts together. The first bit of the "chain" has an additional filler disc which i assume is to prevent the chain from coming into direct contact with the housing case. But because of this disc, the whole chain is actually misaligned and u have to compensate for that extra width by pushing really hard just to open or keep it. Not feasible as a bike chain for daily use at all. Looks fancy, design is sleek, but functionality is crap.
100% satisfied. Fast delivery & very good quality product. Many thanks.
