Purchased seat along with Cruiser scooter. the seat post was dented near the base of post. notified customer support and they sent me a replacement set within a week. outstanding support right there!
installed the base, post, and seat and here's my take. installation was easy. didn't need instructions. adjusting height - no problem. the biggest surprise was that the hydraulic stem provided some very nice softness to the ride and my butt...like shock absorbers. one thing noticeable was there was 'yawing' movement (about an inch of movement) of the seat that attaches to the hydraulic stem. the problem isn't with securing the seat kit but rather the hydraulic stem to the post. you can see the tiny 'play' but more so when seated - like i said, about an inch movement-'yawing' or half inch to left and half inch to right. honestly, i didn't care cuz my butt felt nice on rides (bumpy, smooth, but all paved). plus when riding i didn't even notice it.
