Good on you for discovering the absolute joy of a dropper post. IMO, the darned things should be standard on every trailbike. (For one thing it would help drive the cost of them down.)

Contact Switch is a great value in a hydraulic post - - when they work. Earlier ones were prone to failure; and while they're more dependable than they were, keep a close eye for leaking fluid or balky action. Good news is your Giant dealer should be good about seeking you a speedy warranty replacement if it does go bad on you.

I have a dead one (that I got free - long story) that I wish I could find a replacement gas spring for; but it's a very special size that is not in the usual stock of replacement industrial locking gas springs. Giant evidently contracted a large custom-sized batch. I guess a replacement from Giant for $80 isn't bad since I got the post free; but, still, darned things should only be $30-50.
