I just got my Santori Animaris suspension seat post today and rode about 20mi. with it. I had considered a thudbuster or a body float but I decided to take a chance on this "why pay more" version. https://www.amazon.com/gp/product/B07113WT58/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 I have to say I'm very surprised about the quality and effectiveness of this product on my trekking Haibike. I didn't expect much but it's a LOT better than the cheap zoom pogo stick seat post I had on it initially.
