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 you step all the way down on the stepper, there's a slight metallic clicking 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, the cylinder will be removed before shipping. There are many videos on YouTube about how to handle and train with it, so please refer to those.
