First: It is an original OREGON chain, made in Portland, Oregon, USA. Secondly, it is actually because I had not really dared to hope at that price, an M91-chain (M = Chrome Chisel = multicut), so the semi-professional quality with a longer service life compared to the normal "hobby" -91er chain ( without "M"). Thirdly: has been delivered, in deviation from the specified EAN / SKU M91VX057E, a necklace with number M91VXL057E. The additional "L" indicates that this is the latest version of the proven M91VX with a 33% higher bit length. This should increase the service life again - if it's true, will be seen in the next few weeks. The installation was smooth; any fixed links or other quality problems, which other reviewers had to do, there is not in my chain. At the fourth and final: The chain was appointed in the early afternoon, delivered in the late afternoon and was there the next day. Incredible! That went down like "BodoSchmidt" s cat. Conclusion: Completely satisfied.
