I've probably had the seat post for about a year. I had one before on my father's bike which I rode from time to time, but it seems they've come a long ways since then. When I put one on the Turbo Vado I fell in love with it. I used to stand up for big cracks in the sidewalk or when dropping off pavement onto a dirt path, but now I just float over all those little obstacles while continuing to pedal and without transferring a bunch of shocks straight to my sit bones. It's an odd feeling at first, but I don't feel like I gave anything up for the extra comfort: not speed, not weight, not handling... it just isolates me from small to medium sized bumps. I did have to move my rear reflector a little bit and I moved my second taillight to an under seat mount so it wouldn't interfere with the seat post. Installation was DIY and my post came with a few extra springs to tune it to the rider's weight.
