The unit has made 18 months good services. Soon it begins to squeal, but what you get to grips with appropriate sprays. After 18 months, it has very loud "CRACK!" made and the weld seams of the left footrest recording are chipped. The exercise equipment is no longer usable. Fortunately, the exercisers nothing happened.
Update: equipment has been returned within the warranty free and fast. This service I rate very good and I hope that the new device lasts long.
