### ⭐⭐⭐⭐⭐ Review
*by B***3 on 29 March 2025*

This dropper functions as described. Six month test has gone well as I ride mainly blue trails with the occasional black 2-3 times a week. Only thing to note is I have to slightly stand and relieve tension from post in order for it to drop easier, ie: slightly stand, engage thumb trigger, sit on post to drop. Great post for the budget minded. Highly recommend. Hope this helps. Happy shopping.
