Familiarity: I've used it several times
Got this seatpost with my Yeti SB5c through a recommendation from one of the specialists. I should have read the reviews first. It never has worked properly. Every time I go on a downhill singletrack ride and drop it to its lowest position it never comes back up on its own. I have to help it with my hand. I called and they told me to check the air pressure. I put in more air. 90% of max, still not working. I am waiting to hear back on what to do. I think it is just poorly designed.
