I purchased this item, but I haven't used it much and have been storing it. It's quiet, so you can use it in an apartment without any problems. You can switch between twist mode and aero mode just by changing the lever, allowing you to exercise according to your needs. The step and the entire unit have been cleaned, so you can use it immediately upon arrival. Tokyu Sports Oasis Twist Aero Stepper Premium SP-600 Wood Grain 2-way (Aero Mode, Twist Mode) Quiet
