    Seller was extremely responsive when there was an issue with USPS. It was not their fault, but offered a refund since they didn’t have any additional stock if it hadn’t arrived. Fortunately, USPS just decided to take it on a vacation for an extra couple days. It was packed well, a reasonable price, and brand new as described. Will gladly do business with again.

    Items were brand new in the box as described. Communication was great with the seller, but most of all the shipping was impressive. Had my package in two days. Will definitely do business with the seller again in the future.

    I received exactly what was posted - a brand new Kryptonite 1090 Evolution chain lock. The item came in secure packaging and great condition. It even shipped faster than the estimated delivery date. Can't believe this seller was so much cheaper compared to Amazon and was completely valid too.

    cheaply made

    The pulley wheels are cheap toy plastic without bearing or bushing and the pulley wheels are not bolted in as all derailuers I have seen instead they use this little tiny brad type pin that is slightly dimpled to hold position, I have no doubt in a chain derailment this thing would break that is if it does not cause the derailment to begin with....I"m a mechanical engineer and this thing is a potential danger,,,do not buy
