I bought this unit because I get very little movement in the office. Yes, if it is a very quiet office, you should buy another device. It is also true if you put the unit on a stronger Tretstufe it gets louder and the status of the device is unsafe. But since I only one device for the movement wanted (not for losing weight) abstrampeln and energy, it's made for me as. I stand most of the day, can still speak quite normally, I'm not breaking a sweat. At the end of the day you realize yet that you've done something. Colleagues are jealous. The price is unbeatable.
Can well imagine in the elderly or with limited mobility the leg trainer also. Would it even buy my grandma, so that proper care can achieve more.
