The only drawback was that my saddle was relatively gray, so seemed like faded by the sun. After treatment with SONAX Xtreme Plastic Pfleger (yes, the expensive stuff out of the car accessories) has this now but changed.
Apart from the one-time treatment with og plastic Pfleger I still need to take any management measures for this saddle.
I hope that I can still do a lot of convenient tours with the saddle.
