I purchased these chain in length 55. The quality obtained makes me NOT quality impression. The chain is very easy. A chain weighs 6:30 grams here. Probably one is wertig-feeling chain should weigh rather 10g. The closure affects unstable mounted on me. I hope it holds. The suspension eye is round, not oval. So it fits well with a few Anhängerösen. I had to adapt only with tongs. Soldered it is also reichtlich coarse. I would hope that the offer would also be different levels of quality.
