I have several of those. They are fine as long as you torque down the saddle clamp bolt enough. Looks classic
Never been disappointed with them.
Got a few in the parts box in various scratched states and sizes to help just throw builds together when trying things.
The S65 finish is sublime. It's no lightweight post but I always appreciated the precision of manufacture and quality of fixings. Sold mine over summer, and I would buy again for the right MTB build or Road build over a Campagnolo anyday.
