KS ExaForm Speed Up Hydro Dropper Seatpost - 30.9mm, 175mm, Black

Bought this in early March 2020. Didn’t feel the need for a remote so I decided on this. Great value and recommended to FB friends. At first. By August I noticed that I had to physically pull up on my seat to get it to raise, and it does so slowly. It used to raise quickly under its own power. It still drops fine but it’s a little hassle to raise it when I need to. Maybe I got a dud and will work well for someone else, I don’t know
