The unit was awarded to packed. The assembly instructions was easy to understand. The construction was carried out by me alone. All parts were available and fit well at the designated points. The instrument itself is stable and causes when using the normal rolling and friction noise. Neighbors are likely to be disturbed more by my panting as the equipment noise. Those looking for an inexpensive, yet full-fledged training tool, will definitely be disappointed and find it in no way !!! And do not forget - the fast delivery !!!
