The chain is comfortable and accompanied me in the water. So far, no changes and if they do, vintage is in.
Priced at just under 5 can not do much wrong. The trailer is also reflected well on the rear-view mirror of the car :)
Addendum:
After I had the chain now depend all the time on the car mirror, I have worn in the last 3 weeks around the clock, including for showering. The result was that the chain has lost on both sides of their color, from brown to creamy white. The trailer is thus not dyed or natural, but painted with paint that is not very durable. For the price this but is okay.
