If you want an all-in-one treadmill desk and treadmill go with the TR1200 DT5. This one is too limited in application we fear.
We believe that if you use this one all day you are going to be buying another one in short order. Lifespan is trying to draw people into the whole exercise at work program but we believe that they have missed the mark with the TR800 series. We understand that some people lack the resources to spend another $200 on a better machine but if you are having to repair it all the time, the $200 will be MUCH cheaper on the front end!
