Purchased direct from NordicTrack UK. NordicTrack in their advertisement of the treadmill state “The NordicTrack Commercial 2450 Treadmill is classed as a large boxed item which requires a 3 man delivery so the product can only be delivered to a ground floor room of your choice.” So I was very disappointed and annoyed when the delivery arrived, with only 2 small, not very well built, young delivery boys/men to handle the delivery. Luckily my husband had called home when the delivery had arrived; my husband who is suffering with a hernia had to lift the 125kg treadmill which is not advisable. My husband is now suffering again due NordicTrack not providing or paying for the correct amount of men to deliver this heavy treadmill, which I am sure is a breach of their Health & Safety obligations to the delivery boys/men. Our decorations in the hallway where damaged in the process of bringing in the treadmill. Within the first week of using we have noticed that the fan when turned above speed 2, (speeds 3 – 5) the fan makes an awful vibrating noise, very annoying. The belt needed to be tightened after the first week, the left hand side nut tightened lovely unfortunately on the right hand side the plastic casing hole slot does not line up with the nut, this does not allow the nut to be turned by the allen key, but just damages the nut. This has been reported to NordicTrack - awaiting replacement part. You would have thought that these simple issues would have been spotted by their quality control before the machine was dispatched. Overall a good quality machine which is what you would expect for the money paid just very poor delivery service and simple faults that should have been rectified before delivery.
