Xiser Co. Xiser Pro Trainer Stepper There are some minor scratches and peeling of the plating on the surface, but there are no noticeable scratches or stains. No oil leaks, and no unusual noises during operation. When stepping the stepper all the way down, there is a clicking metallic sound, so the trick is to exercise in a way that avoids that sound! This is a silicone hydraulic stepper with no continuous use time limit. Apparently, the types differ depending on the length of the cylinder, so I've included the measurement results at the end just in case. [Shipping] For safety, we plan to ship with the cylinder removed. There are many videos on YouTube about how to handle and train with it, so please refer to those.
